We will develop superconducting vias for use as bridge crossovers with a novel planar sacrificial MEMS (Micro-Electro-Mechanical Systems) process. The resulting circuit structures will be impedance matched and applicable for use below the superconducting gap frequency commonly in use in planar transmission line circuits.
An ultra-broadband air-gap low-parasitic superconducting crossover circuit be optimized, prototyped, and cryogenically evaluated. We will also explore a innovative via-less design concept based on a 4-port symmetric planar junction.More »
Instrument concepts under exploration for the Inflation Probe, SPICA, and SPECs would benefit from the proposed effort. More generally, end use of this technology has greater applicability and potential to significantly advance reliable routing and signal control in high frequency planar circuitry.More »
