摘要

为了研究多层电阻栅的吸收和散射特性，分析了多层电阻栅在无阻抗面和带阻抗面的介质板中的平面波散射问题，以及多层垂直交叉的电阻栅在自由空间中的平面波散射问题。将所考虑的每个问题转化为一组积分方程，采用矩量法和适当的基函数求解以保证快速收敛。结果表明，所得到的解在入射波和考虑光栅的大范围参数范围内是非常有效的。

Numerical analysis of electromagnetic wave scattering from multilayered resistive strip gratings and its application to wave absorbers

The problems of a plane wave scattering from a multilayered resistive strip grating embedded in a dielectric slab without and with an impedance plane and a multilayered perpendicularly crossed resistive strip grating in free space have been analyzed in order to investigate the absorption and scattering characteristics of resistive gratings. Each of considered problems is converted into a set of integral equations, which were solved by the moment method with appropriate basis functions to ensure a fast convergence. It has been verified that the obtained solutions are very efficient over a broad range of parameters of the incident wave and considered gratings.
