摘　　要：通过电磁波在介质中的传播,以及介质与介质界面处电场和磁场的切线分量的连续条件,分别给出光在介质中传播的传输矩阵以及光在介质界面处的匹配矩阵,从而得到组合结构光子晶体总的传输矩阵,并给出其反射率.在此基础上,研究具有反转对称组合结构为(ABA)N(BAB)M的光子晶体界面态,改变介质A的折射率系数n_(a0)、参数e,厚度d_(a)和周期数N与介质B(葡萄糖溶液)的质量浓度、温度、厚度d_(b)和周期数M以及入射角的大小,给出界面态的位置和峰值大小随参数的变化曲线,并研究葡萄糖溶液质量浓度对组合结构PC_(1)+PC_(2)+PC_(1)和PC_(1)+PC_(2)+PC_(1)+PC_(2)+PC_(1)多个界面态的影响.数值计算结果表明,当改变葡萄糖质量浓度时,可改变界面态的位置和峰值大小,从而实现对界面态的调节.Through the propagation of electromagnetic waves in the medium and the continuous conditions of the tangential components of electric a nd magnetic fields at the interface between the medium and the medium,we gave the transmission matrix of light propagation in the medium and the matching matrix of light at the i nterface of the medium,respectively,so as to obtain the total transmission matrix of the combined structure photonic crystal and their reflectance.On this bas is,we studied the inverted symmetric combined structures for(ABA)^(N)(BAB)^(M) photonic crystal interface states.By changing the refractive index coefficient n_(a0),parameter e,th ickness d_(a) and period number N of the medium A,as well as the mass concentration of medium B(glucose solution),temperature,the thickness of d b and period number M,and the size of the incident angle,we gave the location of the interface state and the peak size curve along with the change of these pa rameters,and studied the effects of the mass concentration of glucose solution on multiple interface states of combined structures PC_(1)+PC_(2)+PC_(1) and PC_(1)+PC_(2)+PC_(1)+PC_(2)+PC_(1).The numerical calculation results show that the location of the interface state and peak size can be changed when the mass concentration of glucose is changed,thereby achieving the adjustment of the interface state.
