Spectral domain characteristic basis function method for efficient simulation of microstrip devices in layered media

In this study the authors present a novel technique in the context of the characteristic basis function method (CBFM) for the efficient analysis of microstrip circuits and antennas printed on layered media. The proposed approach, defined herein as spectral domain CBFM (SP-CBFM), improves the CBFM performance by providing a fast and accurate method to reduce the total computational time required to generate the reduced matrix. Numerical examples are presented to demonstrate the reliability and the efficiency of the described procedure in terms of accuracy and time saving.
