摘要: 结合经典电磁场理论和Bloch定理,讨论了光波在周期性层状结构材料中传播的色散关系,并通过传输矩阵方法得到光波的透射谱,指出在周期性层状结构中波阻抗是形成光子带隙的本质因素.

关键词: 光子晶体, 光子带隙, 折射率, 波阻抗

Abstract: Interaction energy and force between two coaxial rings are obtained. The spatial distribution diagram for force is plotted. Variation of the force with distance and radius of the rings are discussed as weel.

Key words: coaxial rings, interaction energy, force, elliptic integral
