Claims
- 1. A dielectric resonator comprising:a cavity housing; a support mounted within the cavity housing; a first dielectric half disk resonator structure mounted on the support and having a straight edge wall with a dielectric/air interface positioned adjacent to the straight edge wall, wherein the straight edge wall and the dielectric/air interface approximate a magnetic wall thereby creating an electromagnetic image of the electric field within the half disk resonator structure.

The resonator of claim 3, wherein the magnetic wall of the first dielectric half disk resonator structure and the magnetic wall of the second dielectric half disk resonator structure intersect such that the electric fields of the first half disk dielectric resonator structure and the second half disk dielectric resonator structure are coupled.
- 6. A dielectric resonator, comprising:a first cavity containing a first dielectric half disk resonator structure, the first half disk resonator structure having a first straight edge wall and a first dielectric/air interface associated with the first straight edge wall; a second cavity containing a second dielectric half disk resonator structure, the second dielectric half disc resonator structure having a second straight edge wall and a second dielectric/air interface associated with the second straight edge wall; a cavity wall separating the first cavity from the second cavity; and an iris structure formed on the cavity wall coupling the first cavity to the second cavity, wherein the first dielectric/air interface interacts with the first straight edge wall to approximate a magnetic wall thereby creating an electromagnetic image of the electric field within the first half disk resonator structure and the second dielectric/air interface interacts with the second straight edge wall to approximate a magnetic wall thereby creating an electromagnetic image of the electric field within the second half disk resonator structure.
- 7. The resonator of claim 6, wherein the straight edge wall of each dielectric half disk resonator structure is isolated from the cavity wall.
