Furthermore, the phrase, “at least one” preceding the Markush groups is to be interpreted that the group does not exclude one or more additional elements preceded by the phrase.

Common features of FIGS. 1 to 39 and 83 to 89, 96 to 101.

The components as shown in the drawings can have different layouts, proportions, orientations, materials, etc. Features shown and described in the drawings and the description can be combined, interchanged, multiplied, etc. Some features can be omitted to maintain functionality of the proposed embodiments.

Energy can be transferred through electrical field coupling and/or magnetic field coupling. Electrical current flowing through a primary circuit can create electromagnetic fields in a primary electromagnetic interface. The primary electromagnetic fields can create secondary electromagnetic fields in a secondary electromagnetic interface. The secondary electromagnetic fields in the secondary electromagnetic interface can generate electrical current in a secondary circuit. Primary/secondary electromagnetic interfaces can provide a return path for magnetic fluxes which can propagate (in air, in a liquid) outside the primary/secondary electromagnetic interfaces. A primary electric field in the primary circuit providing condenser action can create a secondary electric field in the secondary circuit. Electrical current flowing through a primary circuit coupled with a primary coupling inductor, capacitor or electromagnetic coupler can create a primary electromagnetic field which can create a secondary electromagnetic field around a secondary coupler which can generate a secondary current in a coupled secondary circuit. The created secondary magnetic fields can oppose the creating primary magnetic fields and the created secondary electric fields can oppose the creating primary magnetic fields to preserve energy. The fields can be resonant or non-resonant according to the present invention.

The invention proposes a repeating electromagnetic interface which in fact can be considered as a specific primary/secondary interface in a system which can perform receiving and transmitting function (eventually other functions of primary/secondary electromagnetic interface/e.g. with different parameters, etc.).

The primary and the secondary electromagnetic interfaces can have a strong (proximity) coupling [e.g. with a coupling factor k>0.1] or a loose (vicinity) coupling [e.g. with a coupling factor k<0.1] when spaced apart from each other to be able to transfer electromagnetic fields in a predominantly non-radiative direct field (resonant or non-resonant) coupling or energy transfer can use predominantly radiative coupling. The lay-out, pattern, dimensions, shapes, numbers, etc., of the primary/secondary electromagnetic components can shape electromagnetic field surrounding electromagnetic interfaces and electromagnetic fields confined within the primary/secondary electromagnetic elements, similarly for electric fields. The shielding can function as a reflector [especially at higher frequencies between 100 MHz and 300 GHz]. e.g. in a parabolic, a 3D modelled form/e.g. conical, pyramidal, diagonal, cavity-backed, etc. wherein sidewalls may be straight, shaped, curved, etc./, custom shaped or it can be a planar reflector, etc.

The system can provide dual orthogonal sense linear polarization configurations by adding a replica of a respective (dipole) antenna system and rotating that system 90° wherein components in both directions can have different dimensions.

Overall design and material choice of the primary/secondary electromagnetic interfaces [e.g. reducing sharp edges and corners, preferably chamfering, radiusing the edges/corners of the primary/secondary magnetic elements, evenly disposing primary/secondary components in selected patterns, choosing a convenient thermal management system, etc.] and of the whole system can provide uniform electromagnetic field distribution and reduce or eliminate electromagnetic fields hot spots.

Energy transfer can be perturbed in the presence of an extraneous object which can influence coupling and result in energy losses. Optimisations of the system can avoid or alleviate perturbations.

The system can use energy transfer repeaters, energy relays, etc. Repeating electromagnetic interfaces can provide energy to devices [e.g. to a heating upholstery of a car] and can simultaneously pass a portion of received energy onto other device in the system [e.g. to a clothing of a person in the car]. The repeaters can receive an electromagnetic energy through a first electromagnetic field with a first plurality of parameters and can generate a second electromagnetic field with a second plurality of parameters. The repeaters can be multiplied to extend the distance range of the system. The repeated electromagnetic fields can have different frequencies from the first electromagnetic fields.

Various applications of the system can have various useful energy exchange and energy transfer efficiency demands. The system can use a passive compensation method and adjustable elements [e.g. in active tuning, autotuning, controlling tuning circuits, etc.] to provide acceptable (economical, tolerable/within environment limits, size limits, cost restrictions/, etc.) energy transfer efficiency. The system can use detuning, frequency hopping, time multiplexing techniques to decouple [e.g. to reduce voltage, current, power transfer, to protect devices with lower power demand from overheating, to protect a heated object from overheating, to defend the system from unauthorised power transfer, to enable authentication of energy sources and coupled loads in the system, etc.].

The system can use inductors, capacitors, distributed inductance, distributed capacitance, distributed filter banks, or combinations [e.g. capacitively loaded (coupling) inductors, etc.]. The components can be fixed or variable, can vary impedance matching, a resonant frequency, etc. The components can be connected in series (resonant or non-resonant circuits) or in parallel (resonant or non-resonant circuits). The embodiments of the electromagnetic interfaces can provide (distributed) inductance, (distributed) capacitance and combinations.

The elements of the invention on a primary side and on a secondary side can be differently sized, oriented [e.g. parallel, substantially parallel, offset, rotated, etc.], structured, coupled, etc. Geometric parameters and distance among primary and secondary electromagnetic interfaces may considerably influence coupling factor. A radiation energy transfer can be reduced if the size of the system components [primary/secondary magnetic elements, primary/secondary conductors, primary/secondary coupling inductors, etc.] can be much less than the wavelength of system operation. Shaping, shielding, sizing, orienting the primary/secondary electromagnetic interfaces [which can be sub-wavelength objects] together with tuning, frequency range and other system parameters setting can help to design electromagnetic fields, to alleviate losses [e.g. primary/secondary conductor absorptive losses, radiation losses, absorption losses/e.g. in extraneous objects/, etc.] and to optimize the system efficiency which can be learned by practicing the invention. The primary/secondary electromagnetic interfaces and their elements can be separated by a thickness of an insulation, a dielectric layer, etc. and can be spaced apart by any distance in which the system can be able to transfer at least partially the electromagnetic fields.

An electric field of a primary/secondary capacitive or electromagnetic coupler which can be a good conductor can be completely perpendicular and a magnetic field can be tangencial and composed of one or more circular magnetic fluxes. Electric field of the primary/secondary coupler providing condenser action can be provided between parallel portions of the primary/secondary conductor [e.g. within a dielectric layer] and can be perpendicular to the circular magnetic fluxes in the primary/secondary magnetic elements. An electron flow between the parallel portions (electrodes) and/or an electric current in the primary/secondary conductor can create circular magnetic fluxes in the primary/secondary magnetic element and vice versa.

A primary/secondary [and terciary, etc. in case of a repeater] magnetic field created by respective primary/secondary circular magnetic fluxes [and terciary fluxes, etc.] can advantageously provide homogenous and (highly) directive electric and magnetic fields or can provide omnidirectional patterns. Directivity can be a significant advantage in applications where the power is only required to be directed over a small area and can prevent it, for example causing interference to other users. Devices coupled with a secondary [and terciary, etc.] magnetic field can have a certain orientation freedom in a 3D space in relation to a position of a primary electromagnetic interface. The orientation freedom can be biggest around an axis (substantially) parallel to the axis of rotation of the primary circular magnetic fluxes and in directions (substantially) perpendicular to the axis which corresponds to a biggest orientation freedom concerning electric fields.

Primary/secondary capacitive or electromagnetic couplers can be (substantially) parallel oriented at about and/or in primary/secondary magnetic elements and/or can be orthogonally, convergently, divergently, focus, random oriented, etc., or combinations. A coupling side of a primary/secondary magnetic element and/or of the primary/secondary conductors [e.g. which can provide internal and/or external condenser action] can be conveniently [e.g. convexly, concavely, cylindrically, etc.] shaped. The primary/secondary electromagnetic field can be in this way correspondingly shaped, the primary/secondary circular magnetic fluxes in the primary/secondary magnetic fields can have a definable plurality of rotation axes. In this way can be formed the relative orientation freedom between energy sources [e.g. charging pads, etc.] and loads [e.g. heating electromagnetic interfaces, etc.].

The primary/secondary conductors [or groups of primary/secondary conductors] can have constant phase, a constant phase 90, 180, etc. degrees out of phase, a variable phase, etc.

The system can be used in a two-coupler energy transfer systems or in multi-coupler systems. A bipolar structure (four-plate structure in case of a capacitive or an electromagnetic couplers) can include primary and secondary electromagnetic interfaces working pairs (groups) which can be provided in a four-plate structure or in any other orientation and pattern. The four-plate structure can be provided in a stacked configuration. In unipolar, bipolar (or other) structures the primary electromagnetic interfaces can have different size, orientation, insulation, shielding, circuitry, etc. than the secondary electromagnetic interfaces. The desired condenser action between capacitive or electromagnetic couplers can influence primary/secondary couplers' shaping, dimensions, etc., used dielectric layers, etc. The condenser action provided between electrodes within a same interface can increase the self-capacitance and voltage stress (a reliable electrical insulation can be a good option or necessity).

The primary and the secondary electromagnetic interfaces can be relatively planar to be integrable into planar electronic devices. Applications of the system can imply heat [e.g. hysteresis loss, energy transfer induced heat, or ambient heat/e.g. when used in tires, etc./. The elements/e.g. binders, polymers, wires, etc. can be fabricated of appropriate heat resistant materials and/or provided with appropriate thermal insulation, etc. The primary and the secondary magnetic elements together with the primary and the secondary conductors and shielding can be designed to be flexible, scrollable, foldable [e.g. can be embedded, integrated, etc. into flexible enclosures/e.g. clothes, cushions, etc./. The primary/secondary magnetic elements can be comprised of elastomers containing magnetic particles, and the like, and the primary/secondary conductors can be fabricated of tressed wires, and the like.

The primary/secondary conductors can be switchable, or can be in a switchable groups. Some of the primary/secondary conductors can be dedicated for a power transfer and others for a signal (data) transfer and provide communication.

The primary/secondary magnetic elements and/or the primary secondary conductors and/or the shielding can be shaped to match various installations [e.g. engineering constructions, furniture, street furniture, etc.], devices [e.g. home appliances, tools, packages, etc.]. They can curve to follow the contours of the device, they can fill a dedicated space within the device, etc. They can have various geometries, shapes, enhancements, ridges, indentations, notches, etc. The primary/secondary electromagnetic interfaces can be shaped to provide a multidirectional energy transfer in a multidirectional area.

Magnetic materials that have ferromagnetic or ferrimagnetic properties can magnify magnetic flux density and can add additional magnetic flux to the already existing flux. Ferrite materials typically show a hysteresis effect between the applied magnetic field and the resulting field. The flux magnification effect of a ferrite rod depends on both the relative permeability of the ferrite material used, and on the form factor, for example the diameter to length ratio. The gyromagnetic effects of certain materials such as ferrite can also be used to increase the circular magnetic flux. The system components can convert electric energy to magnetic energy and back to electric energy. The provided electromagnetic field characterised by the circular magnetic fluxes can be resonant or non-resonant and the system can have a preset coupling coefficient for various applications. Resonance can be achieved within the primary/secondary/repeating electromagnetic interfaces (antennas) and/or with coupled (compensation) electrocomponents.

The system can include an oscillator to convert DC energy into radio frequency energy [e.g. in the frequency range from around 20 kHz to around 300 GHz] and can function at defined frequencies [e.g. about 135 kHz, 200 kHz, 600 kHz, 1 MHz, 6.78 MHz, 10 MHz, 13.56 MHz, 21 MHz, 27.12 MHz, 40.68 MHz, 10 GHz, etc.]. The frequencies for power transfer can be unmodulated.

The electromagnetic energy transfer systems can be enclosed in magnetically permeable packaging, in low-lossy (non-lossy) materials (e.g. certain plastic, carbon fiber, composites, plastic composites. Teflon, Rexolite. ABS (Acrylonitrile butadiene styrene). PVC (Polyvinyl chloride), nylon, rubber, acrylic, polystyrene, ceramics, stone, etc.). The packaging can comprise air, gas, sand, insulation, etc. The plurality of primary and/or secondary magnetic elements and/or primary and/or secondary conductors can be integrated into one device and similarly on a primary side can be one device transferring power to a number of devices on a secondary side or vice versa.

The system can provide wireless data transmission which can provide communication through some form of modulation of the signal [e.g. analog/amplitude, frequency, phase/, digital/amplitude, frequency phase shift keying/, etc.]. Communication can utilize various wireless short range or long range carriers and protocols. Wireless communication can use primary and secondary (eventually repeating) electromagnetic interfaces, a Near Field Communication (NFC), a Radio Frequency Identification (RFID), a Wireless Personal Area Network (WPAN) [e.g. Bluetooth, ZigBee), a Wireless Local Area Network (WLAN) [e.g. Wi-Fi], a Worldwide Interoperability for Microwave Access (WiMax), wireless telephone technologies [e.g. 4G, 5G, etc.], a satellite connection. Communication can further be optical, [e.g. laser, infrared, etc.], acoustic [e.g. underwater acoustic communication, etc.]. Communication can use a separate channel from the circular electromagnetic field or can be combined with the circular electromagnetic field.

Common features of FIGS. 40 to 82 and 90 to 95.

The shown apparatuses illustrate the proposed microwave heating method for a heating system comprising a primary electromagnetic interface including a microwave energy generator and a secondary electromagnetic interface including one or more electromagnetic conductors conducting the microwave energy and/or transforming electromagnetic waves into heat.

High-frequency current has a tendency to become distributed near the surface of a conductor. The skin effect can be characterised by the skin depth. The skin depth at which the current density has fallen to 1/e of that at the surface (e=2.718; the exponential constant) may be calculated upon the electrical conductivity, frequency and permeability and is inversely proportional to the electrical conductivity, frequency and permeability. Resistance of the conductor is determined by material's resistivity, a cross sectional area and a length. Resistance decreases as the cross sectional area increases and the resistivity decreases under the same length. The higher the resistivity the higher the joule loss and the heating effect. Resonance sharpness increases as the resistance and Joule loss decrease leading to increasing of microwave energy transfer efficiency. Circuit cumulative energy and circuit energy consumption can be calculated according to specific demands on energy transfer and energy transformation into heat of a system. Various materials can be used as base materials of conductors such as brass, copper, silver, aluminium, steel, etc. Various metals can be used as plating materials such as nickel, iron, copper, silver, etc. Surface plating thickness may be taken into consideration when calculating conductive or heating parameters of the system [e.g. nickel plating can have greater Joule loss than a copper plating at a same thickness, etc.].
