计算光子晶体态密度的程序，与文献吻合，只要小的修改就可计算其他结构的态密度-photonic crystal calculation of the density of states procedures, in line with the literature, as long as minor modifications other structures can be calculated density of states

光子晶体态密度，非常好用，修改几个参数就可以拟合出想要的结果。(Photonic crystal density of states, very easy to use, you can modify several parameters fit the desired result.)
