Abstract

The theory of the self-consistent treatment of vortex dynamics developed by Coffey and Clem is extended to the case of anisotropic type-II superconductors. The vortex response to a microwave electromagnetic field is theoretically investigated based on the associated complex rf magnetic permeability of anisotropic superconductors. Microwave dissipation due to vortex motion is studied as a function of the temperature, dc magnetic field, and microwave frequency. Comparisons of numerical results between anisotropic and isotropic superconductors are also given. The influence of the thin edge of superconducting platelets on the microwave properties is specifically examined as well. The extension presented provides the possible applicability in studying the high-frequency response of real anisotropic high-temperature superconducting single-crystal platelets in the mixed state.
