Effective surface impedance of a high temperature superconductor

In this work, we will investigate theoretically the effective surface impedance of a high temperature superconducting thin film in the microwave range. This investigation will be according to varying the thickness of the superconducting thin film and the operating temperature, based on means of impedance transformations. The microwave surface impedance is related to the fundamental properties of high-Tc superconductors. The study of surface impedance has two important aspects. The first one is the real part of the surface impedance; the surface resistance determines the electromagnetic power dissipation through the superconductor thin film. The second is the imaginary part of the surface impedance; the surface reactance is proportional to the magnetic-field penetration depth.
