| 摘 要： | 利用传输矩阵方法模拟了正负折射率材料交替生成的多层膜体系的反射率对不同偏振模式的角度和频率响应。结果表明，该体系具有很宽的反射带，并且反射带不会随着入射角度的变化而发生平移，可以用来制作高品质的宽带全方位反射镜。

| Abstract: | By means of transfer matrix method,the numerical simulation and analysis for the properties of light propagation in multi-layers structure with alternative layers of negative refraction materials and positive refraction materials have been made in this paper.The reflectance response to incident angle and frequency in different polarization modes were calculated.It's shown that the structure has wider reflective band which is different from the case of traditional quarter-wavelength stacks and the reflective band doesn't move with incident angle.Based on these unique properties,the multi-layers structure containing negative refraction materials can be used as broadband omni-directional reflector. |
