Abstract
A quasi optical resonator consisting of two spherical mirrors and a new cal ibration technique were developed to measure the surface resistance Rs and its distribution of high temperature superconductor (HTS) at 94GHz. The Q f actor of the open resonator is greater than 1.4 x 10(5), and the radius of Guass beam waist is 2.53mm. This method has advantage of being nondestructi ve, high sensibility, convenient experiment setup.
