A hybrid mechanism water-based metamaterial (HMWM) with polarization conversion, absorption and phase cancellation mechanisms is proposed in this paper. The absorption and polarization conversion mechanisms are integrated by combining the water layer with polarization conversion structure, and the absorption conversion rate reaches more than 90% in the dual band (4.0-4.7 GHz and 8.2-15.7 GHz). Based on the above mechanism, the phase cancellation mechanism makes use of the opposite phase between HMWM and its mirror structure for checkerboard con...
