comsol仿真计算发射和反射波，并在第一和第二衍射级作为入射角为一个导线栅的电介质基片上的角度的功能的衍射效率。平面波的入射角扫从垂直入射到掠入射。本申请还示出了用于发病的一个选定角度的多个光栅周期的电场范图。(This application computes diffraction efficiencies for the transmitted and reflected waves and the first and second diffraction orders as functions of the angle of incidence for a wire grating on a dielectric substrate. The incident angle of a plane wave is swept normal incidence to grazing incidence. The application also shows the electric field norm plot for multiple grating periods for a selected angle of incidence.)
