摘要/Abstract

摘要：

通过外加与电磁波传播方向垂直的磁场来调控等离子体光子晶体的光子带隙结构。采用时域有限差分方法数值分析了由本征层为等离子体层和其他电介质材料层交替堆叠而成的磁化等离子体光子晶体的光子带隙结构和频谱特性。数值结果表明，光子晶体中等离子体的介电常数随着外磁场大小的变化而改变，从而使磁化等离子体光子晶体的带隙特性在一定的频率范围相应地得到调节。

Abstract:

The photonic band gap (PBG) structures of plasma-based photonic crystals (PPCs) can be turned after adding a perpendicular magnetic field. The PPCs consisting of intrinsic plasma layers and other dielectric material layers stacked alternately, is taken as an example in studying photonic band gap structures and transmission spectra within the magnetic field using finite-difference time-domain algorithm. The numerical results illustrate that the dielectric constant of the plasma is modified differently in different frequency ranges and the PBG characteristics of the PPCs are turned correspondingly.

Key words: Plasma photonic crystals, Photonic band gap, Transverse magneto-optical effect, Finite- difference time-domain
