Abstract

High-Tc superconducting (HTS) materials have ultralow surface resistance values at microwave frequencies, which have been applied to make high-Q resonators and 'super filters' with narrow-bandwidth, low insertion losses, and superior out-of-band rejections. The second important property of HTS materials is related to low-noise Josephson junctions made from the HTS thin films. In recent years, novel nonlinear high-frequency devices, most of them exploiting the unique features of the AC Josephson effect, have been developed. Applications of the HTS devices based on Josephson junctions have been extended from lower electromagnetic bands (microwave) into mm-wave and terahertz, regions. An overview of CSIRO's recent research activities and achievements in developing novel HTS devices for applications to wireless communication and imaging is presented in this paper.
