中文摘要：
利用传输矩阵法研究了单负材料一维光子晶体（AB）m（ADBDB）n（AB）mA的透射谱,发现：透射谱中出现2个共振隧穿模,其位置和间距可由周期数m或n,以及介质层厚度d调节控制。改变m,会出现2个恒定间距的共振隧穿模;改变dA,共振隧穿模间距增大,且当dA≥25mm时,间距增大加剧;改变n,共振隧穿模逐渐趋于简并,当n≥6时,两隧穿模合二为一;改变dD,两共振隧穿模亦逐渐趋于简并,当dD≥20mm时,两隧穿模亦合二为一。这些特性可为利用光子晶体设计可调性高品质单通道、双通道滤波器提供参考。
英文摘要：
By means of the transfer matrix method,transmission spectra characteristics of single-negative materials with one-dimensional photonic crystal（AB） m（ADBDB） n（AB） mA was researched,and the results showed that the location and space of two resonant tunneling modes can be adjustably controlled by the number of period m or n,and the thickness d of medium layers.Changing m,two resonant tunneling modes of constant space show up;changing dA,the space of them increases,and the space increases more severely when dA≥25 mm;changing n,the two resonant tunneling modes tend to degenerate and become one unit when n≥ 6;changing dD,they tend to degenerate and become one unit when dD≥20 mm.These characteristics can provide references for designing the adjustable high-quality single-channel and double-channel filters.
