Claims
- 1. A high frequency (exceeding 1 MHz) electromagnetic detector comprising a detecting loop; first and second gaps arranged symmetrically in said loop; first and second voltage doublers located respectively in said first and second gaps for completing a circuit and providing a rectified output; and connection means connected across said first and second voltage doublers for causing cancellation of any E-field pick-up in the loop.
- 2. A detector as set forth in claim 1 further comprising a measuring means connected to said first and second voltage doublers.
- 3. A detector as set forth in claim 1 wherein said loop is mounted on a polyguide so as to be two dimensional and said detector being constructed so as to be used with the E-field horizontal (perpendicular to the gaps) and the B-field perpendicular to the polyguide.
- 4. A detector as set forth in claim 3 further comprising a measuring means having first and second terminals; said first terminal being connected to said first voltage doubler; and said second terminal being connected to said second voltage doubler.
- 5. A detector as set forth in claim 4 wherein the connections to said measuring means are each semiconducting lines.
