Description
Summary:A numerico–analytical method for calculating the eigenwaves of striplines, making it possible to obtain numerical results with high accuracy at low computational costs, is developed. An algebraic model of a microstrip line in a multilayer dielectric medium is constructed. The elements of the matrix of a system of linear algebraic equations are transformed into rapidly converging series. Asymptotic expressions for the matrix coefficients and an asymptotic solution of an infinite system of linear algebraic equations are obtained. The results of a numerical analysis of the convergence of the method, confirming its efficiency, are presented.
