Analysis of Frequency Selective Structures with Fractal Elements

Abstract

It is shown the possibility of development of multifrequency frequency selective surfaces (fss) by means of complicating of the shape of elements. For example using elements with composite fractal shape. In the paper the method of integral equations is applied for the analysis of scattering characteristic of these gratings. In the paper the possibility of applying of fss with elements of the composite shape at development of multifrequency fss with reduced angular sensitivity on the basis of numerical experiment is shown. The obtained results can be used for choosing the most rational version of element shape of fss at a solution of some problems in antenna engineering.
