摘要: 当前研究设计的超表面吸波器(MSA)具有良好的电磁(EM)波吸收特性，然而很少考虑入射电磁波形式和功率的影响。该文提出一种在相同频率下可以选择性吸收特定脉冲波的非线性电路MSA。设计的MSA单元结构由集成二极管与电阻电容并联的非线性电路的金属方环形谐振器，中间介质基板隔离层和底部接地层组成。结果显示该MSA对50 ns的短脉冲波在3.2 GHz吸收率可达97%，而对应同频率下的连续波吸收率只有21%。在3.2 GHz附近，该MSA对50 ns短脉冲波吸收率随着功率不同而动态调节且总保持在60%以上，而对应的连续波吸收率只固定在20%左右。当增大脉冲宽度时，设计的MSA吸收率先增大后显著减小。功率为0 dBm和–4 dBm的脉冲波TE模和TM模斜入射情况下，设计的MSA吸收率仍然超过60%。进一步的研究结果表明该MSA对短脉冲波吸收特性严重依赖于非线性电路电容以及单元结构几何参数设计。该研究在无线通信、抗电磁干扰、电磁兼容等领域具有潜在的应用前景。Abstract: The current design of the MetaSurface Absorber (MSA) has excellent absorption characteristics of ElectroMagnetic (EM) wave. However, the influence of incident EM wavefrom and power is rarely considered. In this paper, a nonlinear circuit based MSA is proposed, which can absorb selectively wave with specific waveforms at the same frequency. The unit-cell structure of the proposed MSA is composed of a metal square ring resonator integrated with a nonlinear circuit of four diodes parallel with one resistor and capacitor, an intermediate dielectric substrate (Rogers4350) isolation layer and a bottom ground plane. The results show that the designed MSA can achieve an absorbance of 97% of the 50 ns short pulse at 3.2 GHz, while the corresponding one of the continuous wave is only 21% at the same frequency. Around 3.2 GHz, the absorbance of 50 ns pulse can be dynamically adjusted by changing incident pulse power, and the absorbance is always above 60%, while the corresponding one of the continuous wave is only fixed at about 20%. When the pulse width of the incident wave is increased, the absorption level of the designed MSA firstly increases and then decreases significantly. In the case of oblique incident wave of TE and TM modes with 0 dBm power and −4 dBm, the absorbance of the designed MSA is still more than 60%. Further research results show that the absorption characteristics of the MSA is depend heavily on the design of capacitance as well as the geometric parameters of the unit-cell structure. This research has potential application prospects to wireless communication, anti-EM interference, EM compatibility and other fields.
