Paper Abstract

A versatile microwave/millimeter-wave characterization technique using cylindrical resonance cavities has been implemented which allows measurement of the absorption and sheet resistivity of high-temperature superconductor (HTS) powders, films, and bulk samples. Copper and YBa2Cu307_x (1-2-3) powders were compared with bulk samples to provide input for a simple model of microwave conductivity in bulk HTS materials. While the conductivity of copper metal is more than twice that of bulk YBa2Cu307_x at 77 K, the conductivity of copper powder at this temperature is less than that of the HTS powder.
