Cylindrical eigencurrents
Abstract
The eigenvalue problem for the integrodifferential operator associated with the electromagnetic scattering by conducting surfaces is solved for the case of long finite circular cylinders. The approach consists of reducing the eigenvalue equation to matrix form using the Galerkin technique, expanding the resulting matrix elements in an asymptotic series in inverse powers of the cylinder length, and then applying perturbation theory.
