摘要： Highly sensitive infrared detectors can be made from superconducting micrrip transmission lines, having a single ground plane, a dielectric substrate on the ground plane, and a thin film path of superconducting oxide on the substrate. These microstrip transmission lines can be fabricated into resonant or non-resonant structures. The detectors operate by detecting changes in a microwave signal transmitted through the microstrip, measures in the amplitude, frequency or time domains. An embodiment of this invention is an asymmetric ring interferometer, with or without a metal segment in the shorter leg of the interferometer. Another embodiment of this invention is a meander path transmission line, which, in certain configurations, may be used as a single element array with very high resolution in the direction parallel to the meander lines.

摘要： A microwave switch is provided for controlling the transmission of microw energy in a microstrip transmission line structure. The microwave switch comprises an electrically conducting ground plane in contact with one side of an undoped semiconductor material having on its other side a superlattice of gallium arsenide consisting of a periodic sequence of p- and n-doped gallium arsenide layers. P- and n-type regions are formed integral with and electrically connected to the superlattice, and first and second microstrip transmission lines are electrically connected to respective ones of the n- and p-type regions.
