摘要:

提出了一种新型的光子晶体,其通过将交替的石墨烯和电介质盘的组成堆叠的周期性阵列嵌入到背景电介质介质中而形成。计算了这种光子晶体的能带结构和透过率。石墨烯基光子晶体可以有效地用作电磁波谱远红外区的频率滤波器和波导。由于掺杂石墨烯中低频辐射吸收的实质性抑制,光子晶体中的阻尼和趋肤效应也被抑制。讨论了石墨烯基光子晶体的优点。

英文摘要:

A novel type of photonic crystal formed by embedding a periodic array of constituent stacks of alternating graphene and dielectric discs into a background dielectric medium is proposed. The photonic band structure and transmittance of such photonic crystal are calculated. The graphene-based photonic crystals can be used effectively as the frequency filters and waveguides for the far infrared region of electromagnetic spectrum. Due to substantial suppression of absorption of low-frequency radiation in doped graphene the damping and skin effect in the photonic crystal are also suppressed. The advantages of the graphene-based photonic crystal are discussed.
