ARMA/FDTD technique for reflection properties of periodic structures at oblique incidence and developing wide angle EBG application

Metamaterials including Meta-surface are widely researched to enhance antenna applications. Electromagnetic Band Gap (EBG) structure and Frequency Selective surface (FSS) are one of the meta-surface. In order to enhance the antenna properties, the meta-surfaces are used near the antenna. In this situation, reflection characteristics at oblique incidence are important properties. On the other hand, the meta-surface are composed by periodic structures. In this paper, the reflection properties of meta-surface at oblique incidence case are researched by using ARMA/FDTD technique. Furthermore, we will indicate wide angle EM absorber which based on EMG.
