Iteration method for calculating the characteristic admittance matrix of multi-conductor transmission lines

Abstract

It is necessary to solve the square root of the LC matrix when calculating the characteristic impedance matrix of multi-conductor transmission lines. This letter presents an algorithm based on the simple iteration method. There are no strict requirements for selecting initial values, which means that any initial value can converge to the correct solution. Based on this algorithm, a program is developed, and the solution is in agreement with other algorithm results.
