Abstract
In this work, an analytical method to calculate an improved reference impedance to reduce the computational cost in a fast S-parameter convolution method is presented. The method is based on the definitions of S-parameters and is originally used to calculate the approximate characteristic impedances of transmission lines with modified ground structures. Test cases show that the developed method improves the overall computational cost by roughly 29–65 % with only a small computational overhead.
