Abstract

This work presents a design procedure for a simplified geometric quasi-fractal FSS, that starts with the analysis of the effect of several geometry details (small gaps) on the frequency behavior. Firstly FSS structures are numerically analyzed, using the Wave Concept Iterative Procedure (WCIP). Secondly they are experimentally characterized. Thereafter a comparison between simulated and measured results is performed, as well as an investigation of the effect of the FSS geometry on the resonant frequency using the electric and magnetic field distributions, the latter through the electrical current density vector.
