A new technique for efficient simulation of RF and microwave circuits in layered media using the Equivalent Medium Approach combined with CBFM

In this paper we present an efficient technique for analyzing RF and microwave circuits printed on layered media. The method is based on combining a new Equivalent Medium Approach (EMA) - which obviates that need to construct layered medium Green´s functions - with the Characteristic Basis Function Method (CBFM). A numerical example, which illustrates the accuracy and efficiency of the proposed approach when applied to a typical microstrip problem, is included in the paper.
