This work aims at description of the optimization process of frequency selective surfaces. The method of moments is used to analyze the planar periodic structure and thus to estimate the corresponding transmission coefficients. The algorithm of Levenberg-Marquardt is chosen as a local optimization method. The approach of combination of the method of moments and optimization allows to automate the whole process of the filter design and frees the users from the detailed knowledge of the filter design theory. This work also contains an example of a band-stop filter which is optimized to reflect the Wi-Fi signal. S-parameters of the initial and optimized filters are presented in the paper.
