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

摘要

The present invention relates to asuperconductive electromagnetic wave mixer comprisinga local-oscillator section and a recciving section,said receiving section serving as a section at whichan electromagnetlc wave from the local-oscillatoraection and an externally originating electromagneticwave are combined. The local-oscillatorsection and said receivins section are each formed by atleast one Josephson junction employing at least oneoxide superconductor.
