Quasioptical Josephson Oscillator

摘要

The Quasioptical Josephson Oscillator (QJO) is a 2-D array of between 100 and1,000,000 Josephson junctions, each at the center of a small dipole antenna. HYPRES, Inc. of Elmsford, NY has fabricated test chips which have demonstrated 0.35 microwatts radiation at 190 CHz in one case, and 0.7 microwatts radiation at 345 GHz in another case. A significant understanding of the 2-D oscillators was developed through theoretical and numerical calculations. (AN).
