Nanophotonics, Vol 11, Iss 6, Pp 1177-1185 (2022)
Tailoring the wavefronts of spoof surface plasmon polaritons (SSPPs) at will, especially with multifunctional integration, is of great importance in near-field photonics. However, conventional SSPP devices suffer from the issues of bulk configuration
