Scattering of Electromagnetic Waves in a Spinor Formalism. II. Comments on the Eikonal Approach to Scattering from Coated Perfect Conductors,
Abstract
The eikonal approach is applied to the problem of the scattering of scalar and electromagnetic waves from an excluded volume in the presence of a weak external potential. In the case of scalar (Schroedinger) waves, a compact closed form for the scattered wave function is derived. The scattering of electromagnetic waves is treated in the spinor formalism previously developed by the author. The excluded volume is eventually taken to be a perfectly conducting cone, the external potential a coating of thickness delta, with complex dielectric constant epsilon primed, and permeability mu (tacitly assumed equal to 1). It is shown that to order (N-1), where N = square root of (epsilon (primed) mu), the eikonal approach in the spinor formalism yields results equivalent to those obtained from the vector theory of Uberall in the particular case of nose-on backscattering, using the eikonal function corresponding to straight-line propagation.
