We experimentally demonstrate a type of waveguiding mechanism for coupled surface-wave defect modes in a surface-wave photonic crystal. Unlike conventional spoof surface plasmonwaveguides, waveguiding of coupled surface-wave defect modes is achieved through weak coupling between tightly localized de...
