In this paper, a flexible ultrawideband metamaterial absorber (MMA) with multiple perfect absorption peaks has been proposed and investigated. In this design, we choose the rubber as the dielectric layer to achieve flexibility and select the split square ring to reach multiple perfect absorbing peaks. For the simulation results, the three-layer absorber that reaches 90% absorptivity has achieved 3.87 to 10.84 GHz. Then, we propose a five-layer absorber for easy facilitation, whose absorptivity reaching 90% has achieved 3.78 to 9.85 GHz, and the absorption peak has reached 99.99%, 100%, 100%, and 99.99% at 4, 5.82, 8.46, and 9.71 GHz, respectively.
本文提出并研究了一种具有多个完美吸收峰的柔性超宽带超材料吸收器（MMA）。在该设计中，我们选择橡胶作为介电层以实现柔性，并选择裂环方环来实现多个完美吸收峰。对于仿真结果而言，吸收率达到90%的三层吸收器在3.87至10.84GHz范围内实现了该吸收率。然后，我们提出了一种便于制造的五层吸收器，其吸收率达到90%的频段为3.78至9.85GHz，并且在4GHz、5.82GHz、8.46GHz和9.71GHz处的吸收峰分别达到了99.99%、100%、100%和99.99%。
