Microwave coupled excitation of solid state resonant arrays
View Patent ↗An electronic receiver array for detecting microwave signals. Ultra-small resonant devices resonate at a frequency higher than the microwave frequency (for example, the optical frequencies) when the microwave energy is incident to the receiver. A microwave antenna couples the microwave energy and excites the ultra-small resonant structures to produce Plasmon activity on the surfaces of the resonant structures. The Plasmon activity produces detectable electromagnetic radiation at the resonant frequency.

a microwave antenna; and
an array of solid state resonant structures proximate to but not touching the microwave antenna to couple energy from the microwave antenna to the resonant structures to thereby produce resonant Plasmon activity on the surfaces of the resonant structures at a resonant frequency higher than the highest frequency in the microwave frequency range, the solid state resonant structures in the array being arranged in a path spaced apart from each other in a vacuum environment and having a physical dimension less than said wavelength of the resonant frequency higher than the microwave frequency.
