【Abstract】 Due to the higher requirements of high throughput and large bandwidth for 6G wireless communication and space situational awareness(SSA) systems, terahertz technology has gradually become a research hotspot in worldwide academic and industrial fields. Spoof surface plasmon polaritons have strong field confinement in sub-wavelength region and nonlinear dispersion characteristics for the transmitted electromagnetic waves, bringing new opportunities for the realization of terahertz functional devices and system applications. In 2022, terahertz spoof surface plasmon polaritons received considerable attention in the development of passive devices, active devices, sensors, 6G communication and biomedical systems. This paper reviews the hotspots of terahertz spoof surface plasmon technology in 2022.更多还原
