Patent ID: 8884725

Claim:
A device comprising: an evanescent-mode electromagnetic-wave cavity resonator comprising: a lower cavity portion having an inner cavity surface and a mating surface around the periphery of the inner cavity surface of the lower cavity portion, the inner cavity surface of the lower cavity portion having a conductive layer deposited or patterned thereon; an upper cavity portion having an inner cavity surface and a mating surface around the periphery of the inner cavity surface of the upper cavity portion, the inner cavity surface of the upper cavity portion having a conductive layer deposited or patterned thereon, the upper cavity portion and the lower cavity portion forming a volume therebetween, the volume being operable to support one or more evanescent electromagnetic wave modes; and an in-plane lithographically-defined resonator structure having a portion that is located at least partially within the volume so as to support the one or more evanescent electromagnetic wave modes, the resonator structure being formed of a conductive material or having a conductive layer deposited or patterned thereon, an upper mating surface of the resonator structure being mated with, bonded with, or otherwise connected with the mating surface of the upper cavity portion, a lower mating surface of the resonator structure being mated with, bonded with, or otherwise connected with the mating surface of the lower cavity portion, a distal surface of the resonator structure being separated or electrically insulated from the closest surface thereto by a gap distance, a resonant electromagnetic wave mode of the cavity resonator being dependent at least partially upon the gap distance.
