Finite difference method for the numerical solution of electromagnetic waveguide discontinuity problems is presented. The method of boundary relaxation is applied, using finite difference techniques in the nonuniform section of the waveguide and using a modal representation of the field in the uniform sections of the waveguide. To illustrate the process some two-dimensional diffraction problems in an electromagnetic waveguide with rectangular cross section are solved.read more

An Accurate Finite-Difference Method for Higher Order Waveguide Modes
M.J. Beaubien,A. Wexler +1 more
TL;DR: In this article, the authors proposed a finite-difference method solved by successive overrelaxation, which is a very accurate and general technique for dominant mode solution, making minimum demand on computer store, the number of storage locations required being equal to the order of the matrix defining the linear equations used.

An alternating direction method for solving the biharmonic equation.
S. D. Conte,R. T. Dames +1 more
TL;DR: In this paper, an alternating direction implicit iterative method for solving the biharmonic equation was proposed, which appears to be more efficient than any of the known relaxation methods, and is an extension of a method developed by Douglas and Rachford [1] for solving diffusion equations in two or more space variables.

Solution of 2-dimensional field problems by boundary relaxation
I.A. Cermak,P. Silvester +1 more
TL;DR: In this paper, a numerical method is described for solution of 2D electric and magnetic field problems of the exterior type, which is temporarily converted into interior problems by defining an arbitrary closed boundary, and then improving field values on the boundary iteratively, until a solution valid both within and without the artificial boundary is obtained.

Use of Finite Difference Approximations to Partial Differential Equations for Problems Having Boundaries at Infinity (Correspondence)
TL;DR: In this paper, a computationally simple technique is presented for solving finite difference equations arising from potential problems, part of whose boundary is at infinity, making use of an arbitrary "fictitious" boundary drawn close to the regions of physical interest.
