In this letter, an ultra-thin anisotropic metasurface cell with independent control of different polarized waves is introduced firstly. Then different sizes of cells are taken to constituted an anisotropic planar focusing metasurface(PFM) lens with size of 102 &#x00D7; 102mm<sup>2</sup>. Experimental results are in excellent agreement with the simulated(More)
