近年来，超材料得到广泛发展。特别是，EBG 和 AMC 经常用于天线工程。 EBG和AMC被称为超表面，因为这些材料是薄结构。为了设计超表面，使用诸如FDTD方法的数值分析方法。然而，由于超表面的复杂结构，FDTD方法的计算成本变得很大。在本研究中，我们将指出一种有效的建模方法。该方法引入表面阻抗条件来模拟超表面。
In recent years, Metamaterials are widely developed. Especially, EBG and AMC are often utilized to antenna engineering. EBG and AMC are called as Meta-surface because these materials are thin structure. In order to design Meta-surface, Numerical analysis method such as an FDTD method is used. However, calculation cost of the FDTD method becomes large due to the complex structure of Meta-surface. In this research, we will indicate an effective modeling method. The method introduces surface impedance condition to model Meta-surface.
