摘要

我们提出了一种计算多层圆柱体反射的新方法，该方法可用于分析曲面天线罩等非全圆柱体结构。通过使用黑洞方法，结构最内层区域内的场仅用向内传播的波来表示，这对应于在轴上有一个理想的终止(黑洞)。介质筒和介质管的反射计算结果与几何光学计算结果吻合较好。

Analysis of reflection from multilayer cylinder by using a black-hole approach

We propose a new method for calculating the reflection from multilayer cylinders, which is useful in analyzing structures that are not a full cylinder, such as curved radomes. By using the black-hole approach the fields inside the innermost region of the structure are expressed in terms of only inward propagating waves, which corresponds to having an ideal termination (black hole) on axis. The calculated reflection from a dielectric cylinder and a dielectric tube show good agreement with the results obtained by using geometric optics.
