摘要: We propose a method to design transmission-spectrum-controllable spoof surface plasmon polaritons (SPPs) based on the interaction between SPP waveguide and frequency tunable metamaterial (MTM) particles. To achieve MTM particles, we introduce varactor-diodes into split-ring resonators (SRRs). Taking advantage of sub-wavelength scale SRRs, fabricate compact SPPs. Both simulated measured results demonstrate excellent dynamic control transmission coefficients at microwave frequencies.
