摘要
利用一维矩形光子晶体中电磁波横向受限的条件,推导出电磁波在其中各个模式满足的关系式,从而研究了电磁波各模式的特性.通过色散法研究了电磁波的传输特性随模式量子数和矩形边长的变化规律,得出了一些不同于一维非受限光子晶体的新特征,即一维矩形光子晶体的禁带由模式量子数确定,禁带频率中心和频率宽度与模式量子数和边长有关.
Transmission characteristics of electromagnetic wave in 1D rectangle photonic crystal are obtained with restrictions condition of electromagnetic wave and the characteristics of mode are studied.Transmission characteristics of electromagnetic wave are calculated by the dispersion method.The new characteristics of electromagnetic wave in 1D rectangle photonic crystal are obtained.The bandgap of 1D rectangle photonic crystal is determined by quantum number of mode.The center and width of the bandgap are determined by the quantum number of mode and the side length of rectangle.
