摘要

将时域有限差分法与辅助微分方程法相结合,研究了在正折射率介质中由色散超材料组成的二维超材料光子晶体。研究了色散超材料在空气中排列时形成明显的带隙,并阐明了位置和尺寸无序的影响。此外,利用自洽有限差分频域方法,对具有位置无序的2DMPCs进行了特征模态分析。最后,提出了一种二元随机超材料多层反设计的数值方法。

Numerical methods for design of metamaterial photonic crystals and random metamaterials
Two-dimensional metamaterial photonic crystals (2DMPCs) composed of dispersive metamaterials in a positive-refractive-index medium were investigated by incorporating finite-difference time-domain calculations into the auxiliary differential equation method. A distinct band gap was formed and the effects of positional and size disorder when the dispersive metamaterials are aligned in air were elucidated. In addition, using the self-consistent finite-difference frequency-domain method, an eigenmode analysis of 2DMPCs with positional disorder was performed. Finally, a numerical method for the inverse design of binary random metamaterial multilayers was proposed.
