Reflectarray is one of the most suitable options for terahertz (THz) frequency applications, because it can realize high gain with low feed loss. However, conventional metallic reflectarray suffer from significant energy dissipation in metals and dielectric losses in the THz frequency band. To overcome those limitations, a dielectric resonator reflectarray is proposed in this paper. The reflectarray is composed of rectangular columns element with high-resistivity silicon. A multi-frequency phase-matching method is employed in the design, and the simulated results show that the reflectarray has high aperture efficiency and a wide 1-dB gain bandwidth.
