This article proposes a compact spoof surface plasmon polaritons (SSPPs) transmission line, by introducing capacitive loading metal strips to manipulate the dispersion characteristics and electromagnetic field confinement. Results validate that, compared with conventional rectangular‐grooved SSPP structure, the proposed SSPP transmission line features a line‐width reduction up to 53%, and moreover a tighter field confinement, that is, 67% reduction of confinement area. This proposed structure can be further implemented in silicon process with multiple metal layers for on‐chip transmission of terahertz signals.

伪线表面等离子体激元极化传输线，线宽减小，场限制增强

本文通过引入电容性负载金属条来控制色散特性和电磁场约束，提出了一条紧凑的欺骗表面等离激元极化子（SSPPs）传输线。结果证实，与传统的矩形槽SSPP结构相比，拟议的SSPP传输线的线宽减少了53％，而且场约束更加严格，即约束面积减少了67％。可以在具有多个金属层的硅工艺中进一步实现此提议的结构，以实现太赫兹信号的片上传输。
