Electromagnetic coupling
First Claim
1. An electromagnetic coupling comprising:
- a first conductor;
the conductive enclosure enclosing a cavity, wherein the first conductor is inserted into cavity through a first opening in the enclosure;
ground plane within the cavity, the ground plane and the conductive enclosure defining a resonant slot therebetween, wherein the first conductor is electrically connected to the ground; and
a second conductor inserted into the cavity through a second opening in the enclosure;
wherein the conductors are on respective opposite sides of the ground plane within the cavity; and
wherein the first and second conductors are electromagnetically coupled with one another via the ground plane and the resonant slot.

Abstract
An orthogonal electrical coupling relies on electromagnetic coupling for the inner connection, as opposed to direct contact between conductors. A conductor on one of the lines is connected to a ground plane which is adjacent to a resonant slot. Microwave energy is coupled to the slot, thereby exciting the slot. A second conductor is on the opposite side of the ground plane from the first conductor. Microwave energy from the excited resonant slot passes to the second conductor, thereby allowing contactless interconnection between the first conductor and the second conductor. The coupling may emphasize certain modes of propagation relative to other possible modes of propagation. Specifically, the ground plane and slot may be enclosed in a cavity of a size such that the cavity does not support any natural mode propagation inside the cavity. Instead, the coupling may have a cavity in which a transverse electromagnetic (TEM) mode is propagated.
