| 摘 要： | 现有的频率选择表面反射和传输系数对于垂直入射时的反射和传输计算不适用,需加以修正.把入射场分解成与入射平面垂直和平行的极化分量,用散射场的切向分量表示平行和垂直极化波入射时对应的反射和传输系数.该反射系数结构简洁,且适合所有角度的入射波.数值计算结果表明,修正的反射和传输系数与用仿真软件HFSS得到的结果吻合较好.

| Abstract: | The existing reflection and transmission coefficients of a frequency selective surface(FSS) do not apply to calculation of reflection and transmission under normal incidence of waves,and need to be modified.The incident field was decomposed into two components,parallel and perpendicular to the incidence plane,respectively.Consequently,reflection and transmission coefficients were defined by tangential components of the scatter field.The modified coefficients are simple in structure and applicable to incidence at any angle.A numerical result shows that the modified reflection and transmission coefficients agree with those obtained with the commonly used simulator HFSS. |
