Numerical analysis of a Microwave Filter using PJ-FMT-WCIP and 2D DWT-WCIP

Abstract

In this paper, we conduct a comparative study between two numerical analysis methods of RF circuit, Phase Jump-Fast Modal Transform Wave Concept Iterative Process "PJ-FMT-WCIP" and 2D Discrete Wavelet Transform-WCIP "2D DWT-WCIP". Thus, we propose to use the two techniques for the analysis of the same planar structure representing a microwave filter. The first part of this paper is reserved to a brief overview of both methods. The second part is reserved to the use of the methods "PJ-FMT WCIP" and "2D DWT-WCIP" to the analysis of the same structure in order to compare the performances of the two-optimization methods in term of convergence, optimization ratio, average error and computation time. We will end up presenting a summary study in order to conclude on the advantages and limitations of each method.
