二维等离子体填充金属光子晶体腔体特性
|
摘要
设计了等离子体填充的二维金属光子晶体特殊开放腔体结构,并采用粒子模拟技术(PIC)建立了基于等离子体填充腔体结构物理模型,分析了等离子体填充下二维腔体的各模式场分布特性,以及等离子体的引入对腔体内各模式工作频率、电场幅值的影响。结果表明:腔体内各模式的电场强度随等离子体密度的增加而减弱,模式频率随背景等离子体归一化频率的提高而增加,工作模式的产生与激励方式密切相关。
A two-dimensional plasma-filled metallic photonic crystal cavity structure is studied.Particle in cell technique(PIC)is used to establish the physical model.The field distribution properties,the mode frequency and the amplitude of the electronic field are illustrated under plasma-filled situation.Results show that the electric field intensity of each mode in cavity decreases with the increase of plasma density,the mode frequency increases with the increase of the normalized frequency,and different source positions stimulate different modes.
