On the Use of Optimization Techniques in the Design of FSS

Popis výsledku v původním jazyce

Work presented in this paper aims at description of the optimization process of frequency selective surfaces with an example of a Wi-Fi band-stop filter. In this work the method of moments is used to analyse a planar periodic structure. The approach allows to automate the whole process of the filter design and frees the users from the detailed knowledge of the filter design theory. For the practical part of the paper, the algorithm of Levenberg-Marquardt is chosen as a local optimisation method. Whole process of automation is implemented in Matlab. An optimisation of a band-stop filter for Wi-Fi signals serves as a practical example. S-parameters of the final filters are presented in the paper. This work also compares two possible geometries made of simple elements, rectangles. It is a simple cross and a Jerusalem-cross. There is also an interesting note about the quality of these filters using different number of layers.
