RESUMO:

Planar periodic arrays are spatial structures whose filtering properties have attracted the attention of many researchers. These structures are called Frequency Selective Surface (FSS). For decades a variety of FSS for different applications in the field of electromagnetism, has been proposed. The most common applications are: Randomes, antennas and parabolic reflectors. Another important aspect is the analysis techniques. In these analysis, important features are the computational effort and the accuracy. Several analysis techniques can be cited: the equivalent circuit method, the method of moments, the spectral modal analysis and more recently, artificial intelligence techniques combined with optimization algorithms. With respect to recent FSS construction techniques the geometry of the structures, the researchers have given special attention to fractal geometries. These geometries have the advantage of increasing the electrical length and thus reduce its physical dimensions. Another advantage of using these geometries is that many of them feature multiband response with increasing fractal level. This work will be proposed to study new multifractal geometries for application in FSS, analyzing their transmission characteristics and application possibilities.
