摘要
The terahertz band lies between the microwave-millimeter wave band and the optical band, and its related technologies are of great significance for the development of next-generation high-speed communication, high-resolution imaging, intelligent sensor-communication integration systems and other information fields. The development of terahertz application technology requires terahertz beam manipulation and information loading. As a new realization scheme and device, active metasurface is one of the important ways to realize these functions. In this paper, the terahertz dynamic metasurface is classified according to the regulation function of the metasurface, the amplitude regulation, phase regulation, polarization regulation, beam regulation and high-order nonlinear regulation of the terahertz dynamic metasurface are introduced from the complementary materials technology, structure setup, and working mechanisms and their performance in the application demonstrations. The similarity and uniqueness of different types of dynamic metasurface are introduced, and some of the performances are compared. At the end of this paper, the development trend of the terahertz dynamic metasurface is forecasted. It is hoped that this paper helps more scholars get knowledge of terahertz dynamic metasurface hence promoting the development of this field. © 2023 Chinese Institute of Electronics.
