平面波是一种理想的电磁波，许多复杂的电磁波能分解成均匀平面波的叠加形式，研究平面波的传输问题有很强的现实意义，本文利用场匹配法和等效传输线法对平面波入射分成介质问题进行分析，计算出总的反射系数，并利用Matlab软件对频率在0-10GHz的平面波进行了仿真对比，加深了对平面波传输的理解。(Plane wave is an ideal electromagnetic waves, many of the complex electromagnetic waves can break down into a uniform plane wave superposition form, strong practical significance in the study of plane wave transmission problem, this article use field matching method and the equivalent transmission line method for plane wave incident divided into problems with media conduct analysis, calculate the total reflection coefficient, and the use of Matlab software plane wave in the 10GHz frequency simulation compared to deepen the understanding of plane wave transmission.)

This is a code for calculating PSNR of two images.
