摘要

我们研究了二维电磁波通过平面界面的聚焦。从任意三维入射波透射场的精确解出发，导出了聚焦三维波在基尔霍夫近似下的解。在此基础上，对二维电磁波的聚焦问题进行了求解，并对TM场的聚焦特性进行了数值解析研究。

Focusing of two-dimensional electromagnetic waves through a plane interface

We study the focusing of two-dimensional (2D) electromagnetic waves through a plane interface. Starting from the exact solution for the transmitted field due to an arbitrary three-dimensional (3D) incident wave, we derive solutions for focused 3D waves in the Kirchhoff approximation. Then we construct corresponding solutions for focused 2D electromagnetic waves and study in detail the focusing properties of a TM field numerically and analytically.
