Abstract

In this letter, a novel spoof surface plasmon polaritons (SSPPs) bandpass filtering unit (BP-FU) is proposed. The equivalent circuit model of BP-FU is given and by establishing its ABCD-matrix, the pass band and forbidden band are analysed theoretically, which behaves the feature of bandpass. Meanwhile, the simulated dispersion curve of BP-FU shows bandpass feature. Subsequently, the proposed BP-FU is applied to design a bandpass filtering transmission line (TL). The TL obtains the bandpass filtering feature spontaneously due to the periodically arranged BP-FUs. The TL consisting of BP-FUs can be excited by the methods like exciting traditional unit and a transverse magnetic wave propagates along the TL. The field characteristic is as same as classical SSPPs TL. The measured results of the prototype of the TL shows a passband from 6.66 GHz to 10.06 GHz and ultrawide stopbands (

$\vert S_{21}\vert \lt $

-22 dB) from nearly 0 GHz to 5.36 GHz and 10.89 GHz to 40 GHz. The measured results indicate good application prospect in single conductor multifunction circuit.

具有带通特性的紧凑型 SSPPs 装置及其在带通传输线中的应用

本文提出了一种新型欺骗性表面等离子体极化子（SSPPs）带通滤波单元（BP-FU）。给出了 BP-FU 的等效电路模型，并通过建立其 ABCD 矩阵，从理论上分析了其通带和禁带，从而表现出带通的特征。同时，BP-FU 的仿真频散曲线也显示了带通特性。随后，将所提出的 BP-FU 应用于设计带通滤波传输线（TL）。由于 BP-FU 呈周期性排列，TL 自发地获得了带通滤波特性。由 BP-FU 组成的 TL 可以像激励传统单元那样被激励，横向磁波沿 TL 传播。其磁场特性与经典的 SSPPs TL 相同。该 TL 原型的测量结果显示，其通带从 6.66 GHz 到 10.06 GHz，超宽截止带（$\vert S_{21}\vert \lt $ -22 dB）从近 0 GHz 到 5.36 GHz，从 10.89 GHz 到 40 GHz。测量结果表明，单导体多功能电路具有良好的应用前景。
