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 receiving section, said receiving section serving as a section at which an electromagnetic wave from the local-oscillator section and an externally originating electromagnetic wave are combined. The local- oscillator section and said receiving section are each formed by at least one Josephson junction employing at least one oxide superconductor.
