说明：  用传输矩阵法计算光子晶体的透射率,文件中将程序写在word文档中,并附带有在matlab下画的图,程序用matlab编写,感觉很有用,
(use of the transfer matrix method photonic crystals transmission rate, which will write the procedures for word documents, Matlab together with the painting under the plans, procedures using Matlab prepared, I feel very useful,)
