A Design of Dynamically Switchable Spoof Surface Plasmon Transmission Lines with Variable Transmission Characteristics
摘要
Abstract
An electronically controllable spoof surface plasmon polaritons(SSPPs)transmission line with variable transmission characteristics is designed.The dispersion curves of the SSPP unit structure in a state of on-and-off of a diode are analyzed by using an equivalent model based on a dielectric block,and the influence of different unit structure parameters on the dispersion characteristics is also examined.On the basis of these analyses,a SSPP transmission line is designed,simulated,and experimentally meas-ured.The simulation and measurement results show that dynamic switching between passband and stop-band transmission characteristics can be achieved by synchronously controlling the on-and-off state of a PIN diode.Specifically,in the on state of a diode,the passband transmission characteristics are observed with a measured S11 below-10 dB in the frequency range of 2.74 GHz to 9.47 GHz.In the off state of a diode,the stopband transmission characteristics are observed,with a measured rejection level being prior to-20 dB in the frequency range of 4.04 GHz to 5.54 GHz.The experimental results and the simulated results are identical.This work is of great significance for the dynamic control of SSPPs transmission and will greatly promote the development of active SSPP circuits and devices.关键词
