电磁波在光子晶体中介质界面的传输矩阵

Transfer Matrix of Electromagnetic Wave in Medium Interface of Photonic Crystal

为探讨电磁波在光子晶体中两介质界面的传播特点,利用电磁场的边界条件,导出了电磁波在介质交界面传播的传输矩阵,并用此矩阵讨论了透射波和反射波的相位和偏振特征;得到了反射波相位发生突变的条件和布儒斯特定律。

In order to discuss the propagation characteristics of the electromagnetic waves in two medium interface of photonic crystals, using boundary conditions of electromagnetic field, the transfer matrix of electromagnetic wave propagation in the interface of mediums was derived, the phase and polarization characteristics of the transmitted wave and reflected wave were discussed us-ing the matrix. The conditions of phase mutation of the reflected wave were obtained and the Brew-ster＇s law was proved.
