With the advancement of terahertz technology, there is growing anticipation for 6G communication in the international community, and terahertz communication is gaining increasing attention. Nonetheless, terahertz waves possess strong directionality, leading to the obstruction of transmission signals. Consequently, achieving largeangle, directed transmission poses a technical obstacle for terahertz communication. Metasurfaces technology has great potential to improve the coverage performance of 6G networks, making it one of the most promising technologies in this field. This paper designed a terahertz directional reflector that is insensitive to polarization in the terahertz communication band (0.25 THz). The unit structure is selected using the resonant phase modulation principle, utilizing a metal-insulator-metal structure. Following the phase compensation principle, the structure of the unit is arranged and simulation experiments are conducted to achieve a 30-degree abnormal deflection of the reflected beam. This scheme will hold some application value for terahertz 6G channel control in future research.
