摘要

近年来,为了工程目的,在微波和太赫兹频率下对表面等离子激元(SPPs)进行了欺骗研究。由于动量不匹配,SPP模式不能直接从空间模式转换,反之亦然。为了高效率地将空间波导模式转换为SPP模式,已经开发了一些激励方案。另一方面,可能出现的问题是,是否有可能将传播的SPP波转换为定向辐射波进行无线通信?鉴于此,本文介绍了一种基于欺骗spp的微波频率新概念天线。研究了将SPP模式转换为辐射模式的方法,同时提出和讨论了一系列的天线设计。研究了采用SSPP TLs的天线阵列馈电网络。本文综述的大部分工作都是在东南大学完成的。

The engineering way from spoof surface plasmon polaritons to radiations
In recent years, spoof surface plasmon polaritons (SPPs) have been investigated at microwave and THz frequencies for engineering purpose. Due to momentum mismatch, the SPP mode cannot be directly converted from the spatial mode, and vice versa. Stimulating schemes have been developed to transform spatial waveguide modes to SPP modes with high efficiency. On the other hand, the question may arise that, is it possible to transform the propagating SPP waves to directive radiating waves for wireless communication? In view of this, this paper introduces the new-concept antennas based on spoof SPPs at microwave frequencies. Methods of transforming SPP modes to radiating modes are studied, whilst a series of antenna designs are presented and discussed. Feeding networks for antenna arrays using SSPP TLs are also investigated. Most works reviewed in this paper are fulfilled at Southeast University in China.
