Methods of the analysis of microwave circuits with the superdimension scattering matrices

Abstract

The main method of analysis of the microwave circuits is evaluation of their characteristics through the parameters of elements of circuits. The procedure of calculation consists in solving of a system of linear equations (SLE), into which the appropriate coupling conditions are substituted.

With solving the SLE in the matrix form it is necessary to operate with matrices, the order of which is commensurable with a number of the connected ports (inputs).

As the superdimension matrices we understand the matrices, whose dimensions are such, that the technical performances of PC don't allow to operate by them.

One of the effective ways to solve this problem is usage of the cyclic algorithms (CA).
