Surface impedance theory for superconductors in large static magnetic fields


Sherman, Richard David (1971) Surface impedance theory for superconductors in large static magnetic fields. Dissertation (Ph.D.), California Institute of Technology. doi:10.7907/R9YN-V750.


A theory of electromagnetic absorption is presented to explain the changes in surface impedance for Pippard superconductors (ξo ≫λ) due to large static magnetic fields. The static magnetic field penetrating the metal near the surface induces a momentum dependent potential in Bogolubov's equations. Such a potential modifies a quasiparticle's wavefunction and excitation spectrum. These changes affect the behavior of the surface impedance in a way that in large measure agrees with available observations.
