摘　　要：本文利用时域有限差分法(FDTD),计算了不同阵列周期、介质层厚度、介质折射率对V形孔阵薄膜的透射率和法拉第角。计算结果表明,透射谱和法拉第谱随阵列周期的增大会发生明显的红移;介质层的引入提高了透射率和法拉第角,并且可以通过改变介质层(NDL)的折射率和厚度来调控透射谱和法拉第谱,这些结果对磁光器件设计具有重要的意义。In this paper, the finite-difference time-domain method (FDTD) is used to calculate the transmit-tance and Faraday angle of the V-shaped hole arrays film with different array periods, dielectric layer thickness, and dielectric refractive index. The calculation results show that the transmission spectrum and Faraday spectrum will obviously redshift with the increase of the array period. The introduction of the dielectric layer improves the transmittance and Faraday angle, and the trans-mission spectrum and Faraday spectrum can be adjusted by changing the refractive index and thickness of the dielectric layer (NDL). These results have important implications for the design of magneto-optical devices.
