Taking field singularity into account when solving diffraction problems by the method of moments
Abstract
The paper presents a method for taking into account the singularity index in aperture diffraction problems solved by the method of moments. Parvatov and Popov (1980) used the method of moments to solve the problem of TEM-mode diffraction by the aperture of a plane waveguide and to investigate the field within the integration space. In the present paper, this problem is solved using Jacobi quadratures with a uniform division of the integration interval. This makes it possible to analyze the field in the aperture with allowance for singular points.
