With the development of terahertz technology, the global research and anticipation regarding 6G communication based on terahertz waves has gained considerable research attention. However, the transmission of terahertz waves is directional, involves end-to-end propagation, and is often blocked by obstacles. Therefore, realizing wide angle and directional transmission of terahertz waves for communication is technically difficult. Herein, a new metasurface was designed and verified to realize the wide angle and directional reflection of terahertz waves. To realize the focusing function of metasurface and control the phase of light field, the transmission phase modulation principle was adopted in designing the unit structure. This unit structure was arranged based on the lens focusing principle and phase compensation principle. Simulations and experiments were conducted at a working frequency of 220 GHz. Our findings verified that the proposed metasurface can reflect the terahertz waves over a wide angle range of 5°?45° and focus it with a focal length of 600 mm along the direction of 13°. The design scheme proposed provides an effective approach to solve the problems associated with 6G communication based on terahertz waves and has a certain application prospect.
