Analysis of the Electromagnetic Properties of High Impedance Surfaces Using Genetic Synthesis
In this paper, we are interested by the analysis and the synthesis of the high impedance surfaces (HIS), based on periodic arrays of planar conducting elements (FSS) on a dielectric slab backed by a metal surface. The self-resonant grid model is used to analyze the HIS, which allows computing the surface impedance, reflection phases and the propagation properties of the surface waves along the HIS. The synthesis with genetic algorithms (GAs), we search the material characteristics of the electromagnetic structure that ensured the desired performances. Here in, we hope to find the characteristics of the substrate and the grid of FSS which ensure a resonance at a desired frequency and its stability according the angles and the polarisation of the incident wave. Numerical results are presented.
