摘要

提出了一种以圆柱形纳米孔穿孔金属薄膜作为超表面基础的分析研究方法。推导出的公式完全确定了由孔散射的波在离表面任意距离处的电磁场。利用解析公式计算了所研究结构的透射和吸收光谱，以及散射波的相位与孔半径的关系。计算结果与计算量子光电探测器的效率和透镜设计所需的元原子散射光的相变间隔的文献数据一致。

Analytical approach to the problem of electromagnetic wave scattering by a cylindrical hole in a thin metal screen

A method of analytical study of a metal film perforated by cylindrical nanoholes as the basis of a metasurface has been proposed. The formulas deduced completely determine the electromagnetic field of a wave scattered by the hole at any distance from the surface. The calculation of the transmission and absorption spectra of the studied structure, as well as the dependence of the phase of the scattered wave on the radius of the hole, is carried out using analytical formulas. The calculation results are consistent with the literature data for calculating the efficiency of a quantum photodetector and the phase change interval of light scattered by meta-atoms required for lens design.
