Non-reciprocal metasurfaces have recently attracted significant attention due to their ability to control electromagnetic waves in unprecedented ways. In this study, we propose a novel, non-reciprocal metasurface that utilizes a combination of magnetic materials and electrical conductors to achieve non-reciprocity to plane wave illumination at microwave frequencies. Experimental results demonstrate that the metasurface achieves an isolation characteristic of at least 15 dB at 6.5 GHz.
