Popis: We propose a combined structure that can freely control the transmission of spoof surface plasmon polarizations in the terahertz region. The combined structure is composed of a corrugated metallic strip and a textured closed surface with defect units. The spoof surface plasmon polarizations with different frequencies can be effectively trapped by the defect units with different scales in the localized spoof plasmonic structure. The designer structures provide the enhanced ability to modulate the spoof surface plasmon polarizations transmitted in the waveguide, which may provide potential applications in optical switching and sensing in the terahertz region.
