摘要
电磁场同物质相互作用问题可以归结为电磁场同不同折射率形成的"势场"相互作用问题。当电磁场(光子)在周期"势场"中传播时,能量将分裂成带。文章从麦克斯韦方程出发,讨论了电磁场与周期介质的相互作用,并用转移矩阵方法导出了系统的色散关系,描述了周期介质中布洛赫波的传播及系统的稳定性。
The interactions of electromagnetic field with matter can be attributed to the interaction of electromagnetic fields induced by ＂potential field＂ with different refractive indexes.When the electromagnetic field（photon）is propagated in the periodic ＂potential field＂,the energy split into a band.In this paper,the interaction of electromagnetic fields with the periodic media is discussed;and the dispersion relation is derived by the transfer matrix method from Maxwell＇s equations.The Buloch wave propagation in the periodic media and the system stability are analyzed.
