摘要：
The surface conductivity of high temperature superconductors (HTSC) was investigated over the frequency band 2.5-3.0 GHz. The magnetostatic surface waves (MSSW) interaction with a superconductor was applied for this purpose. The absolute value of the conductivity was determined by comparing the numerically - computed and experimentally - measured real and imaginary parts of the wave number. The influence of the air gap between ferrite and superconductor on the value of surface microwave conductivity was investigated. Experimentally it was established that HTSC with structure Y-Ba-Cu-O in the superconducting phase have a finite surface conductivity in the frequency band 2.5-3.0 GHz.
