摘要 为了研究晶体结构对电磁波传输特性的影响,提出了一种空气平板层和圆形复合介质柱混合组成的新型2维混合介质柱光子晶体结构。采用时域有限差分法对其进行了数值模拟和计算,研究了改变混合介质柱的形状和结构参量对晶体透射特性的影响。结果表明,该结构可以基本保留组合前光子晶体的主带隙,并且在新的频段产生新的禁带;在混合结构中将复合介质柱换为简单介质柱没有新的禁带产生。通过改变相关参量发现,增加介质平板的宽度,这增大内嵌介质柱的半径都有利于新禁带的产生。2维混合介质柱光子晶体比单一介质柱光子晶体有更多的可调因素,这为相关光子晶体器件的设计提供了理论依据。 In order to study the effect of the structure of photonic crystal on electromagnetic wave transmission characteristics, a new 2-D hybrid photonic crystal structure was proposed. By means of finite difference time domain method, the optical transmission properties of 2-D hybrid photonic crystals were studied. Furthermore, it was also studied how the shape and structural parameters affect transmission properties of photonic crystal. The results show that the new structure not only maintain the primary band gap of the former structures but also produce a new band gap. Compared to the compound dielectric cylinder, the simple one has not produced a new band gap. Both increasing the width of medium plate and the radius of embedded concentric circle are in favor of the new band gap emerging. The theory basis of the design of photonic devices is provided.
