We calculate the conductor loss of a high Tc superconducting conductor backed coplanar waveguide. The inductance is calculated by the modified Spectral Domain Method(SDM). Then, the geometric factor is obtained by a numerical derivative of the inductance. This factor is used to calculate a conductor loss by the Phenomenological Equivalence Method(PEM).
