论文摘要
超材料具有巨大的潜力，可以为将来的无线通信系统构建超薄，微型化和具有成本效益的微波设备和光学设备。在这里，研究了一个包含四个箭头形晶胞的双波段元用户。在28-36 GHz的微波频谱中对吸收特征进行数值研究和分析。拟议的元吸收室说明了在5G频谱中分别在31.11 GHz和33.77 GHz的相应工作点和相应工作点的两个独立吸收峰分别为96％和99.99％。由于结构对称性，在传入EM波的不同极化角度的影响下，提出的元吸收仪表现出不敏感的极化性能。还分析了吸收仪的吸收特性，以分析入射EM波的不同倾斜度，并在这些工作条件下调整其吸收峰。此外，为了实现这种吸收装置的吸收行为，在上述两个工作频率点上还研究了表面电场谱和电流分布。这种吸收器类型仍然谨慎，可以最大程度地减少5G频段中的MIMO天线元件之间的耦合和串扰。
Metamaterials have great potential to construct ultrathin, miniaturized, and cost-effective microwave and optical devices for future wireless communication systems. Here, a dual-band meta-absorber comprising four arrows-shaped unit cells is investigated. The absorption features are numerically studied and analyzed in a microwave frequency spectrum from 28 - 36 GHz. The proposed meta-absorber illustrates the two independent absorption peaks of 96% and 99.99% at the corresponding operating points of 31.11 GHz and 33.77 GHz, respectively, within the 5G spectrum. Due to structure symmetry, the proposed meta-absorber exhibits insensitive polarization performance under the influence of different polarization angles of the incoming EM waves. The absorption characteristics of the absorber are also analyzed for different obliquity of the incident EM waves, and their absorption peaks are tuned under these operating conditions. Further, to realize the absorption behavior of this absorbing device, the surface electric field profile and current distributions are also studied at the aforementioned two operating frequency points. This absorber type remains prudent to minimize the coupling and cross-talk between the elements of the MIMO antenna operating in the 5G band.
