Analysis on Complex Frequency Selective Surface (FSS) using Finite Different Time Domain Method (FDTD)

Abstract

In this paper, three different situations of the symmetry frequency selective surface (FSS) shaped are designed – consist of without symmetry, 1/4 symmetry and 1/8 symmetry condition using FORTRAN software. In this work, the Energy-Saving Glass (ESG) that covered the glass with a metallic oxide coating to exploit obstructive of infrared and ultraviolet radiation into structures. The tools used in this work were applied to propose a complex shape by using Genetic Algorithm (GA) as the optimization tool to create bits of the chromosome in designing the shape of energy-saving glass (ESG). It also used the Finite Difference Time Domain (FDTD) was working as a process of numerical algorithm modeling to design the complex shape in pixelized shape based on the unit cell idea. For without symmetry complex, 1/4 symmetry complex and 1/8 complex for FSS shape, it shows that the - 43 dB at 1.2 GHz, respectively.
