摘　　要：槽孔导体板电磁波的散射涉及三个过程:首先是电磁波入射到槽孔导体板时发生的反射和透射;其次是透射波在槽孔波导中的传播;最后是来自各个槽孔的透射波的再辐射。基于上述过程,本文提出了一种槽孔导体板准光滤波器的简单设计方法。该方法快速,特别适用于毫米波亚毫米波频段。利用该方法设计了W波段准光圆孔导体板滤波器,实测结果说明了本文设计方法的有效性。Scattering by a dichroie plate depends on three processes： reflection and transmission on the dichroic plate, propagation through holes in the plate, and the radiation from the opening of holes in the plate. Based on the views, a simple design method for dichroic plate filters is presented. The method is fast and suit to use in millimeter wave or submillimeter wave. By means of the method, an W band circular perforated plate filter is designed, fabricated and tested, the results show the effeetness of the method.
