Abstract

The basic physics of superconductivity is reviewed and related to the high-temperature superconductors. The high-frequency characteristics of the new materials are examined, and the two-fluid model is introduced and used to derive an empirical expression for the conductivity of superconductors. The advantages and disadvantages of using these superconductors in the construction of high-frequency transmission lines and passive microwave and millimeter-wave antenna systems are discussed.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
