The optical transmission matrix method is used to deal with the real-time propagation of physical electro⁃magnetic wave through multi-layer homogenized medium.Based on the construction of interface and propagation matrix,the transmission matrix is derived,and the reflection and transmission coefficients are obtained.The propagation properties of physical electromagnetic wave can be analyzed and understood intuitively and comprehensively.For reflective film and DBR(distributed latch mirror),the fitting reflectivity and transmittance are calculated by transmission matrix method and Matlab programming,in order to show the propagation properties and optical characteristics of physical electro⁃magnetic wave in an all-round way.The results show that the matrix mathematical algorithm of multi-layer homogenization medium can be effectively realized based on Matlab programming and transmission matrix method,and the propagation state of electromagnetic wave can be accurately obtained by reflectivity and transmittance.Through the actual case,it can be seen that the organic combination of theoretical knowledge and numerical simulation in physics teaching,and the moderate expansion of the research level is helpful to improve the students practical ability of physics application.
