In this paper, we design and investigate a zigzag reflective multifunctional metamaterial (ZRMM) made by folding a planar metamaterial with horizontal strip structure. It has better absorption and polarization conversion performance compared to planar structures, which can achieve multiple absorption, broad-band cross-polarization conversion, broad-band linear-to-circular and circular-to-linear polarization conversion at different frequencies. Simulation results show that the absorption of the proposed design at 4.48 GHz, 10.54 GHz and 21.02 GH...
