Optimization of the WCIP Method for Multilayer Circuits

This paper presents computational time optimization tools for the Wave Concept Iterative Procedure (WCIP). Throughout the paper, two techniques are presented in order to reduce computational time and reduce the number of iterations necessary to obtain satisfactory results about the resonance and reflection parameters of a multilayer structure. In order to validate the results and ensure the performance obtained, a patch antenna with three interfaces was used, with resonance frequencies at 10 GHz and 14.7 GHz. This multilayer antenna was simulated in the Ansys Electronics Desktop software and compared with the code of the WCIP method applied in Matlab.
