Quasioptical Submillimeter-Wave Sources Based on HTSC Josephson Junctions

摘要

Integrated quasioptical submillimeter-wave oscillators based on high-temperature superconductor (HTSC) Josephson junctions on a bicrystal boundary are designed, fabricated, and experimentally investigated. The junction are integrated with three types of planar antennas: log-periodic, double-dipole, and double-slot. O increase the radiated power, narrow the radiation pattern, and decrease the oscillation line width, the antennas With junctions are incorporated into phased arrays. A cryogenic submillimeter-wave spectrometer and tester are Designed with the use of such sources.
