Dual-Band Orbital Angular Momentum Beam Generator base on the 2-Bit Reflective Metasurface
Orbital angular momentum (OAM) beam has attracted great attention because it can be utilized to improve wireless communication capacity. Therefore, the realization of OAM wave manipulation is of great significance to the development of communication. In this work, a dual-band OAM beam generator is proposed based on the 2-bit reflective metasurface. By arranging the proper phasing elements on the metasurface, we can manipulate the mode and direction of OAM beams at two different frequencies. The simulation results demonstrate that the metasurface has a good performance in generating dual-band vortex beam.
