基于欺骗表面等离子激元和理想吸收体，设计并实现了一种在不同频率下具有吸收和透射特性的混合超材料（HM）.一个单元单元由一个三层的超材料与双正交开口环谐振器和一个接地板加载双面金属凹槽。结果表明，混合超材料主要表现出宽带偏振敏感的吸收从6.57到28.16 GHz的半峰全宽在一个方向上和多频带传输在相反的一个。当入射光平行于HM时，双面金属沟槽的接地板可以支持欺骗表面等离子体激元的结构振动。为了演示设计，HM器件容易实现使用普通的印刷电路板制造方法制造和测量，实验结果与模拟结果吻合得很好。(C)2015 AIP Publishing LLC.
We reported on the design, realization, and numerical characterization of a hybrid metamaterial (HM) with the absorption and transmission at different frequencies based on the spoof surface plasmon polaritons and perfect absorber. A unit cell is composed of a three-layer metamaterial with double orthogonal split ring resonators and a ground plate loaded with two-sided metallic grooves. It is shown that the hybrid metamaterial primarily exhibits a broadband polarization-sensitive absorption from 6.57 to 28.16 GHz with a full-width at half-maximum in one direction and a multiband transmission in the opposite one. When the incidence is parallel to HM, the ground plate loaded with two-sided metallic grooves can support a structural vibration of spoof surface plasmon polaritons. To demonstrate design, a HM device easily implemented using common printed circuit board fabrication method is fabricated and measured and the experimental results agree well with the simulated results.
