Abstract
The application of electromagnetic materials to mobile systems and other platforms requiring complex utilization of radio waves necessitates compatibility with various polarizations. For nonreciprocal metasurfaces that support unidirectional propagation, achieving dual polarization (vertical and horizontal) presents significant design challenges. This study proposes a simple structure for dual-polarization nonreciprocal metasurfaces and presents theoretical and experimental analyses of its performance. As a result, a dual-polarization nonreciprocal metasurface exhibiting high-pass filter characteristics at C-band is realised by incorporating ferrite into a strip line lattice structure, achieving an isolation of 7 dB.
