We propose an anisotropic planar transmitting metasurface,which has the ability to manipulate orthogonally-polarized electromagnetic waves in the reflection and refraction modes respectively.The metasurface is composed of four layered rectangular patches spaced by three layered dielectric isolators each with a thickness of 0.15λ0 at 15 GHz.By tailoring the sizes of the patches,the metasurface functions as a band-stop filter for the y-polarzied wave and a band-pass filter for the x-polarized wave operating from 14 GHz to 16 GHz.Moreover the phases of the transmitting x-polarized wave can be modulated at about 15 GHz,which contributes to beam steering according to the general refraction law.Experimental results are in good accordance with the simulated ones,in which the reflection efficiency is almost 100％ while the transmission efficiency of the x-polarized wave reaches 80％ at 15 GHz.Besides,the transmitted x-polarized wave is effectively manipulated from 14 GHz to 16 GHz.
