Abstract
Currently, most available high-T/sub c/ bulk material is in disk form that does not lend itself readily to microwave-loss measurements. A resonant measurement technique using low-impedance disk resonators is described. The configuration enhances the influence of conductor losses on the resonator Q and thereby permits the evaluation of disks as a function of temperature in a relatively simple test configuration with good accuracy. Measurements on bulk YBa/sub 2/Cu/sub 3/O/sub 6+x/ material are described with conductivities at X-band ranging up to 10 times that of Au at 65 degrees K.<>
