The needed frequency of the blazed grating is in inverse ratio of the incident wavelength. The longer the wavelength, the lower the grating frequency is.
放大所需闪耀光栅的频率与入射单色波长成反比，波长越长，所需光栅频率越低。
In addition, different metals were simulated to generate a lower reflectivity of TM wave, so as to give further discussion on the improvement and applications of such grating.
此外，还比较了不同金属材料光栅的TM波近红外透射特性，探讨了改善其性能的途径。
