OSTI ID:7297465
This patent describes a system for transmitting and/or receiving electromagnetic radiation. It comprises an antenna; a resonant cavity in electromagnetic communication with the antenna; an oscillator, in electromagnetic communication via waveguide means with the resonant cavity; and a modulator, in electromagnetic communication via waveguide means with the resonant cavity, characterized in that the resonant cavity includes a housing having an interior and a superconductor-containing body within the interior of the housing, the body including material which exhibits superconductivity at a temperature equal to or greater than about 77 Kelvins, the body comprised essentially of packed sintered superconductive particles having sizes smaller than one micrometer whereby the body exhibits a smooth conductive surface and a flexural strength of at least 50 MPa.
