Consequently, a polarizationconversion mode is obtained with a high cross-polarization reflection in a broadband region (where the cross-polarization coefficient reaches up to 75 % in the frequency-range of - GHz). The polarization conversion was verified by experiment and the mechanism was clarified by the simulation of induced electric and magnetic fields. Our work could contribute to metamaterial-based multifunctional devices such as filter and polarization modulators. |
