In this letter, we perform numerical and experimental studies of the optical\nresponse of an original configuration based on enhanced transmission through\nguided mode based metamaterials. The proposed structure is inspired by annular\naperture array (AAA) where the cylindrical symmetry is broken in order to\nacquire polarization-sensitive metasurfaces. The experimental results, which\nare in good agreement with numerical simulations, demonstrate that the\nstructure acts as a polarizer exhibiting an extinction ratio of (15:1) with a\nmaximum transmission coefficient up to 85% which is more efficient than what it\nis expected with a typical plasmonic resonance\n
