Submillimeter-wave quasioptical integrated tester based on bicrystal Josephson junctions

摘要

YBCO integrated structures consisting of a planar antenna and a Josephson junction were designed and fabricated on bicrystal sapphire substrates. By combining two such structures in an oscillator-receiver arrangement a submillimeter-wavelength tester was realised. Two types of relatively narrow-band double-slot and double-dipole antennas, a broadband complementary log-periodic antenna and an array of dipole antennas were investigated.
