Busca por padrões inovadores para utilização em filtros especiais à base de Superfície Seletiva em Freqüência.

Abstract

The goal of this project is to find a good method to search new figures de FSS (frequency selective surface) to be utilized in spatial filters. A very common method is the Genetic Algorithms (GAs), which are strongly related to biology, the theory of evolutionism of Darwin and natural selection. We studied this po����e����ful tool to sol����e FSS’s p����o����le����s, running various simulations in CST, and because of this, we studied the macros, which are commands that allows that CST to works automatically using a programming language. In this project, we have chosen the Matlab software to interface with the CST. At the end of the project, we found structures FSS capable to filter signals at frequencies of GSM (900 MHz and 1.8GHz).
