摘　　要：运用直线法对一多层频率选择表面进行了分析。在直线法中,对于FSS各层贴片或孔隙上的感应电磁流,在求得其自身阻抗或导纳矩阵的同时,通过等效传输线理论,得出各层电磁流之间的耦合矩阵,从而为整个多层结构建立方程。对几套不同结构参数的FSS进行了计算,就各结构参数对频率选择表面透射特性的影响作了分析。A multi-layered frequency-selective surfaces （FSS） is analyzed using the method of lines. For the electric or magnetic currents on the patchs or apertures of the multi-layered FSS, the coupled matrix among them can be gained through the generalized transmission-line theory when the self impedance or conductance matrix are gotten in the method of lines, and the equations for the whole structures is established. Some FSS with different parameters are computed, and numerical results are analyzed basically.
