title: Use of indeterminate Padè approximations in the analysis of diffraction at the mirror edges of an optical resonator.
abstract: A method is presented for analysis of the diffraction of waveguide modes at the open end of a two-dimensional metallic waveguide, based on a rational approximation of the field diffracted outside the open end. We believe that this method can be used for waveguides with nonplane walls, and it should prove a useful tool in the analysis of optical resonators.
