摘要

针对传统超表面吸波器（MetaSurface Absorber，MSA）单频带工作、难以区分脉冲波（Pulse Wave，PW）与连续波（Continuous Wave，CW）的局限，本文提出了一种基于全波整流非线性电路的双频带MSA设计方案，其基本单元由三层组成，具体包括顶部加载非线性电路的两个相同尺寸的金属方环形谐振器、中间介质层以及底部金属接地面.通过创新性的电容/电感非线性电路组合，并引入额外并联电感调节谐振频点，构建了4种具有双频带波形选择性吸收效果的MSAs实现方法.这些MSAs可在两个独立频带内精准且独立地吸收特定波形（CW或PW）.且仅需改变并联电感值即可灵活调整工作频带，显著提升了设计的MSAs的工作灵活性与适配性，有效解决了现有电磁吸波器件在复杂多频谱应用场景中的局限性.为使研究具有普遍性，本文以4种类型中的一种双频带MSA作为重点研究对象，即加载电感式非线性电路和加载并联额外电感的电容式非线性电路，重点研究其波形选择特性.首先，通过电磁-电路联合仿真深入探讨了该双频带MSA对不同功率CW与PW的选择性吸收性能，明确功率阈值（-5 dBm）对二极管整流功能及阻抗匹配的关键影响.其次，研究了双频带MSA在不同脉冲宽度下对PW选择性，验证其与电路时间常数的匹配关系.再次，本文对双频带MSA在斜入射横电（Transverse Electric，TE）极化波与横磁（Transverse Magnetic，TM）极化波的波形选择性吸收性能的影响进行了详细分析，证实该MSA具备宽角度稳定性.最后，本文系统地阐述了集总电路元件参数（

、

）对不同波形入射波选择性吸收性能的影响.本文提出的双频带波形选择性MSA，凭借其灵活的频带可调性、稳定的极化与角度适应性，为解决多频带通信中的“脉冲杂波滤除”“频段间干扰抑制”问题提供了有效的技术路径，在天线设计、无线通信信号优化及电磁兼容防护领域具有重要的理论价值与潜在应用前景.

Abstract

To address the limitations of traditional metasurface absorbers (MSAs)

such as single-band operation and the inability to distinguish between pulse waves (PWs) and continuous waves (CWs)

this paper proposes a design scheme for a dual-band MSA based on full-wave rectifier nonlinear circuits. The basic unit of the MSA structure consists of three layers

including two metal square ring resonators of the same size with nonlinear circuits loaded on the top layer

a middle dielectric layer

and a bottom metal ground plane. Through an innovative combination of capacitive/inductive nonlinear circuits and the introduction of an additional parallel inductor to adjust the resonant frequency

four implementation methods for MSAs with dual-band waveform-selective absorption performance are developed. These MSAs can accurately and independently absorb specific waveforms (CWs or PWs) within two different frequency bands. Moreover

the operating frequency bands can be flexibly adjusted simply by changing the value of the parallel inductor

which significantly enhances the operational flexibility and adaptability of the designed MSAs. This effectively overcomes the limitations of existing electromagnetic wave-absorbing devices in complex multi-spectrum application scenarios. To ensure the universality of the research

this paper takes one type of dual-band MSA among the four as the key research object

specifically the one loaded with an inductive nonlinear circuit and a capacitive nonlinear circuit with an additional parallel inductor

and focuses on investigating its waveform selection characteristics. First

the selective absorption performance of this dual-band MSA for CWs and pulse waves PWs with different powers are thoroughly explored through electromagnetic-circuit co-simulation

clarifying the critical influence of the power threshold (-5 dBm) on the rectification function of the diode and impedance matching. Second

the selectivity of the dual-ban

d MSA for pulse waves under different pulse widths is studied

verifying its matching relationship with the circuit time constant. Subsequently

a detailed analysis is conducted on the influence of oblique incidence of transverse electric (TE)-polarized waves and transverse magnetic (TM)-polarized waves on the waveform-selective absorption performance of the dual-band MSA

confirming that this MSA exhibits wide-angle stability. Finally

this paper systematically elaborates on the influence of lumped circuit component parameters (

) on the selective absorption performance of the MSA for incident waves with different waveforms. The dual-band waveform-selective MSA proposed in this paper

with its flexible frequency band tunability and stable polarization/angle adaptability

provides an effective technical approach to address the issues of “pulse clutter filtering” and “inter-band interference suppression” in multi-band communications. It holds significant theoretical value and potential application prospects in the fields of antenna design

wireless communication signal optimization

and electromagnetic compatibility (EMC) protection.
