| 摘 要： | 简要介绍了利用谱域伽略金法计算平面频率选择表面传输系数的方法。该方法以平面波谱展开和傅里叶变换为基础,在谱域中应用弗洛凯定理建立方程。采用屋顶基函数作为子域基函数表示感应电流,通过矩量法求解频率选择表面上的感应电流,进而求得传输系数。给出了某工程使用的单环频率选择表面的设计,计算结果与测试结果一致。

| Abstract: | The analysis on the transmission coefficients of frequency selective surface by the spectral domain Galerkin method is introduced briefly,which is based on the outspread of the plane wave and Fourier transform.The equation in spectral-domain is established by applying the Floquet＇s theorem.The surface current is expressed by using roof-basis function.The surface current and transmission coefficients can be got by this method.The transmission coefficients of a single ring frequency selective surface are measured and calculated.A good agreement between them is given. |
