Abstract: A novel 2-bit coding metasurface for terahertz beam steering is proposed here. By fractionally dividing the phase gradient distribution, a higher-precision beam steering has been implemented. Compared with uniform coding manner, the novel non-uniform coding strategy employed on the proposed metasurface can shorten prominently the step length of beam steering, highly being valued for high resolution imaging and detecting.
