Abstract
In the past few years, the orbital angular momentum (OAM) has aroused great interests within scientific communities, showing great potentials to enhance capacities in radio, optical and quantum communications. Here an anisotropic coding metasurface is proposed to generate multiple polarization controllable OAM vortex beams at microwave frequencies. A phase compensation theory is put forward to determine the array pattern of the metasurface, enabling the generation of vortex beams with arbitrary polarization. The metasurface is composed of anisotropic elements, whose reflection phases can be engineered and encoded separately along different polarization directions. The simulation results demonstrate that multiple OAM vortex beams can be generated as expected, with each of them polarized in a controlled manner. The proposed avenue shows great potentials for the application of polarization division multiplexing in OAM communication systems.
