摘　　要：光的偏振是大学物理光学部分的重要内容,光的偏振特性被广泛应用于生物检测和传感等领域.以布儒斯特定律为例,展示了数值模拟在光的偏振部分教学中的应用.利用基于有限元分析法的Comsol软件,论文首先通过数值模拟清晰地呈现了自然光和线偏光以布儒斯特角入射时在两种不同介质表面的反射和折射特性;进而通过在棱镜表面镀高低折射率交替的多层介质膜的方式实现了偏振光分束.借助数值模拟,学生能更好地理解相关知识,同时还学会利用数值模拟拓展相关知识的应用.The polarization of light is an important content of physics,which is widely used in the daily life,biological detection and sensing.In this paper,Brewster′s law is taken as an example to demonstrate the application of numerical simulation in teaching.With Comsol software based on finite element analysis,it is clearly presented with numerical simulation that the reflection and refraction properities of natural light and linearly polarized light incident on the surface of two different medium at the Brewster angle.Then,polarized light beam splitting is realized by plating multilayer dielectric films with alternating high and low refractive index on the prism surfaces.With the help of numerical simulation,students could better understand the relevant knowledge,and learn to use numerical simulation to expand the application of the related knowledge.
