FREQUENCY CONVERTER

摘要

A frequency converter for electromagnetic waves of the millimetric and submillimetric band comprising an open resonator whose reflectors are of diameter larger than the dimensions of the cross-section of radiation beam, said reflectors or at least one of them being an arrangement of metallic conductors and to said conductors being connected one or more Josephson junctions. Said conductors are equipped with external contacts situated on the circumference of the converter and used to interconnect the Josephson junctions. The converter finds applications as a detector of electromagnetic waves of the millimetric and submillimetric band and/or as a mixer of waves of different wavelength.
