Multifunctional reflection type anisotropic metasurfaces in the terahertz band
Based on the convolution and superposition theorem, we propose a reflective anisotropic metasurface to realize the functions of deflection and superposition of vortex beams, bifocal focusing, and focusing vortex beam. At frequency of 1.04THz, two deflection vortex beams with topological charges of (...
