Abstract

An ultrathin metal strip consisting of connected split-ring resonators (SRRs) is proposed which can tune the dispersion of spoof surface plasmon polaritons (SPPs) by varying the gap widths of the SRRs. It is found that the decrease of the gap width leads to a remarkable red-shift of the dispersion of spoof SPPs. The underlying mechanism can be interpreted from the resonance properties of a single SRR and two connected SRRs. As an application, we experimentally demonstrate that spoof SPPs with different frequencies can be slowed down gradually and stopped at different positions by introducing a graded SRR structure with a linearly increased gap width, and thus, a slow-light “rainbow” is observed.
