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 GHz are 94.76%, 97.90% and 99.60%, respectively. In 14.43 GHz–20.32 GHz, cross-polarization conversion can be achieved well. Similarly, excellent linear-to-circular and circular-to-linear polarization conversion have been achieved at 10.98 GHz–13.96 GHz. This metamaterial can be used as an absorber and polarization rotator. It can be used for antennas to change the polarization of radiated waves, as a frequency selective surface, or to reduc...

具有条形结构的之字形反射多功能超材料吸收器和偏振旋转器

在本文中，我们设计和研究了通过折叠具有水平条形结构的平面超材料而制成的之字形反射多功能超材料（ZRMM）。与平面结构相比，它具有更好的吸收和极化转换性能，可以在不同频率实现多重吸收，宽带交叉极化转换，宽带线性至圆形和圆形至线性极化转换。仿真结果表明，所提出的设计在4.48 GHz，10.54 GHz和21.02 GHz的吸收率分别为94.76％，97.90％和99.60％。在14.43 GHz–20.32 GHz，可以很好地实现交叉极化转换。同样，在10.98 GHz–13.96 GHz上也实现了出色的线性-圆形和圆形-线性极化转换。这种超材料可以用作吸收器和偏振旋转器。它可以用于天线来改变辐射波的极化，作为频率选择表面，或者用于降低频率。
