提出了一种基于欺骗表面等离子体（SSP）模式的微波慢波传输线的理论模型，并对其进行了实验验证。等效电路模型首先用于表征SSP结构，并发展为在给定截止频率和布洛赫阻抗下设计SW-TL的有洞察力的指导方针。为了保证微带传输线的准瞬变电磁式模式逐渐转化为SW-TL的工作瞬变电磁式模式，必须提出将传统微带传输线与SW-TL连接的模式变换器。所提出的SW-TL原理图为集成电路的互连体体积小型化和电磁兼容性的增强，例如多层单片微波集成电路，开辟了一条有前途的道路。
This paper presents a theoretical model and validates experimentally the microwave slow-wave transmission line (SW-TL) based on spoof surface plasmon (SSP) modes. Equivalent circuit models are first presented for characterizing the SSP structures and developed to serve as an insightful guideline to design the SW-TL at a given cutoff frequency and Bloch impedance. A mode converter connecting a conventional microstrip transmission line to the SW-TL is necessarily proposed to ensure that the quasi-TEM modes of the microstrip line are gradually transformed to the operating TM modes of the SW-TL. The presented schematic of SW-TL paves a promising avenue for the unprecedented interconnector footprint miniaturization of integrated circuits, and the enhanced electromagnetic compatibility, for example, in multilayered monolithic microwave integrated circuits.
