摘要

为了支持电磁兼容测试和测量,本研究提出了一种单波段手性超材料吸收器作为电磁兼容吸收器的解决方案。在x波段(8.2-12.4 GHz)分析了一种由新月形裂环谐振器组成的新型手性超材料吸收体。为了补充所提出的吸收剂,还考虑了不同的损耗正切(δ)值。反射光谱和吸收光谱表明,在共振区周围,高性能的吸收水平接近统一(最大吸收)。所提出的吸收剂可以找到需要超薄吸收剂的应用,并且由于其构造超薄1.2 mm (0.04λ),因此可以成为有前途的应用的良好候选者。所有仿真均在CST Microwave Studio环境下使用频域求解器进行。此外,通过改变该结构的几何参数,可以将其扩展到红外波段。

Planar chiral metamaterial absorber composed of new crescent shaped split ring resonators
To support EMC test and measurements a single band chiral metamaterial absorber is suggested in this study for EMC absorber solutions. We analyze a novel chiral metamaterial absorber composed of crescent shaped split-ring resonators at the X-band (8.2–12.4 GHz). To supplement proposed absorber, different loss tangent (δ) values are also considered. Reflection and absorption spectra illustrated high-performance nearly unity absorption levels (maximum absorption) around resonance region. The proposed absorber can find applications in which ultra-thin absorbers are needed and can be a good candidate for promising applications since it is constructed ultra-thin 1.2 mm (0.04λ). All simulations are performed by CST Microwave Studio environment using frequency domain solver. Besides, by changing the geometrical parameters of proposed configuration, it can be scaled up to infrared bands.
