Abstract

In this paper, we present a method for extending the bandwidth of a metamaterial absorber (MMA) with multi-resonance structure. The basic unit cell of the MMAs consists of a periodic arrangement of an electric-LC (ELC) resonator and a square loop structure. The absorption bandwidth of a MMA is effectively extended by combining five unit cell structures with different geometric dimensions into a co-planar unit cell. Experimental results show that the fabricated MMA is 0.8 mm (0.0026λ0) thick with a peak absorption rate of 93% at 10 GHz, and a full width at half maximum (FWHM) bandwidth of 940 MHz.

具有扩展带宽配置的超材料吸收器

本文提出了一种扩展具有多共振结构的超材料吸收体(MMA)带宽的方法。MMAs的基本单元由一个周期性排列的电lc (ELC)谐振器和一个方形环路结构组成。通过将5个不同几何尺寸的单元胞结构组合成一个共面单元胞，有效地扩展了MMA的吸收带宽。实验结果表明，制备的MMA厚度为0.8 mm (0.0026λ0)，在10 GHz时峰值吸收率为93%，半峰宽(FWHM)带宽为940 MHz。
