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

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
