PERTURBATION METHODS IN A PROBLEM OF WAVEGUIDE THEORY

Abstract

The reflection coefficient for the basic mode in a widening, straight, two-dimensional waveguide is computed for small wave numbers by using the perturbation method with the electrostatic case as the unperturbed case. Essential features of the treatment are the use of conformal mappings, the consideration of physically unreal modes, and the inversion of an infinite matrix. (Author)
