Abstract

In this paper we have developed a numerical technique to carry out the full wave analysis of a generalized microstrip line on an inhomogeneous substrate. We use the finite difference method to express the problem in the form of a sparse matrix equation. A model order reduction technique is used to express the problem in terms of a smaller matrix. This is accomplished using the bi-Lanczos algorithm. The overall complexity of the algorithm is O(N1.5). Storage requirements can be made to scale as O(N) making it possible to analyze large problems on small computers. Very good agreement is seen between published results and the results obtained using this technique.
