摘要

从先进色散工程相关应用的角度出发，介绍了一种由两个介质层组成的二维体积(即非平面)结构，该结构由多周期网格上的各种金属夹杂物加载，并由两个受限金属平面封闭。全波模拟已经被用来证明，对于轴向传播，该结构呈现出(i)大的电磁带隙和(ii)在不同频段具有反平行相位和群速度的两种模式，并且它们不与其他模式相互作用。

2D periodic structure featuring negative group velocity of bloch waves

A 2D, volumetric (i.e., non-planar), structure consisting of two dielectric layers, loaded by various metal inclusions on multiple-periodic grids and closed by two confining metal planes is introduced in view of advanced dispersion engineering related applications. Full-wave simulation has been used to demonstrate that, for axial propagation, the structure presents (i) a large electromagnetic band-gap and (ii) two modes that have anti-parallel phase and group velocities in different frequency bands where they do not interact with other modes.
