Full-wave analysis of arbitrarily multilayered planar structures by the method of lines

This paper presents a hybrid differential method for analyzing multilayered planar microwave structures based on the method of lines using a nonequidistant discretization. The flexibility of this method is increased substantially. As a consequence the accuracy is improved with reduced computational effort. There is no restriction on the number of strips nor on the number of dielectric layers. Our formulation uses the full-wave analysis, which does not involve quasi-static approximation. Computational results show good agreement with those presently available in the literature.
