Abstract

Traditional electromagnetic (EM) wave absorbing materials are often constrained by narrow absorption bandwidths due to their overly simplistic loss mechanisms. In contrast, spirulina, an ancient photosynthetic organism dating back billion years, has evolutionarily developed superior EM wave absorbing capabilities through its unique helix microstructure. By mimicking this natural design, we proposed a helical metamaterial absorber and fabricated it by 3D printing process, achieving an ultra-wide effective absorption bandwidth of 33.7 GHz (covering 3.5–5.1 GHz and 7.9–40 GHz, reflection loss RL ≤ −10 dB). The excellent microwave absorption performance originates from the material's dielectric loss capability and the unique EM response of the helical structure. The distinctive EM response encompasses: periodic induced current rotation generating eddy currents, localized electric-magnetic resonance, and standing wave effect. This bio-inspired paradigm bridges evolutionary optimization with artificial metamaterial design, demonstrating transformative potential for next-generation radar stealth systems and EM compatibility engineering.

一种用于宽带电磁波吸收的生物启发螺旋超材料

传统的电磁吸波材料由于其过于简单的损耗机制，往往受到狭窄的吸收带宽的限制。相比之下，螺旋藻是一种可以追溯到数十亿年前的古老光合生物，通过其独特的螺旋结构进化出了优越的电磁波吸收能力。通过模拟这种自然设计，我们提出了一种螺旋状的超材料吸收体，并通过3D打印工艺制作，实现了超宽的有效吸收带宽33.7 GHz（覆盖3.5-5.1 GHz和7.9-40 GHz，反射损耗RL≤−10 dB）。优异的微波吸收性能源于材料的介电损耗能力和螺旋结构独特的电磁响应。独特的电磁响应包括：产生涡流的周期性感应电流旋转、局部电磁共振和驻波效应。这种受生物启发的范例将进化优化与人工超材料设计相结合，展示了下一代雷达隐身系统和EM兼容性工程的变革潜力。
