SUPERCONDUCTIVE ELECTROMAGNETIC WAVE MIXER AND SUPERCONDUCTIVE ELECTROMAGNETIC WAVE MIXING APPARATUS EMPLOYING THE SAME

摘要

The present invention relates to a superconductive electromagnetic wave mixer comprising a local-oscillator section and a recciving section, said receiving section serving as a section at which an electromagnetlc wave from the local-oscillator aection and an externally originating electromagnetic wave are combined. The local-oscillator section and said receivins section are each formed by at least one Josephson junction employing at least one oxide superconductor.
