Abstract
We propose a generalized London theory that can correctly describe the longitudinal and transverse responses of conventional superconductors to an electromagnetic field. The continuity equation is satisfied by use of a special gauge for the scalar and vector potentials. Our phenomenological theory provides a simple example of the Anderson-Higgs mechanism.
