摘　　要：利用介质材料的色散关系和特征矩阵法研究了一维光子晶体中TE波和TM波的全反射隧穿效应随色散的变化特征.TE波和TM波全反射隧穿导带的频率中心随色散强度的增加而降低,频率宽度随色散强度的增加而增大.TE波和TM波的全反射隧穿导带的频率中心随入射角的增加而升高,频率宽度随入射角的增加而减小.这些研究结果拓宽了对一维光子晶体中TE波和TM波波全反射隧穿效应的认识.Using the dispersion relation and the characteristic matrix method,dispersion characteristics of the total reflection tunnel of TE wave and TM wave in 1D photonic crystal are studied.The total reflection tunnel frequency center decreases with the increase of the dispersion intensity,and the total reflection tunnel frequency width increases with the dispersion of dispersion intensity.The total reflection tunnel frequency center increases with the dispersion of incident angle,and the total reflection tunnel frequency width decreases with the dispersion of incident angle.These findings expand the understanding of the total reflection tunnel of TE wave and TM wave in 1D photonic crystal.
