A Dual‐Loss‐Suppression Meta‐Unit for Low‐Loss Continuously Tunable Spoof Surface Plasmon Polaritons

ABSTRACT Dynamic tuning of spoof surface plasmon polaritons (SSPPs) is typically accompanied by substantial loss, which mainly originates from two sources: parasitic loss in tunable semiconductor components and dielectric loss dominated by the substrate. Here, we propose a contin...
