研究和设计了一种亚波长波纹金属波导，以减缓太赫兹频率的光。波导由两个平行的薄金属板组成，其内部边界有周期性的波纹。与基于工程表面等离子体的结构相比，该结构具有更小的群速度色散和更低的传播损耗。本文还解释了慢波的起源。
A subwavelength corrugated metal waveguide is studied and designed to slow down the light at terahertz frequencies. The waveguide consists of two parallel thin metal slabs with periodic corrugations on their inner boundaries. Compared with structures based on engineered surface plasmons, the proposed structure has smaller group velocity dispersion and lower propagation loss. The origin of the slow wave is also explained.
