Abstract

Highlights

The energy conversion mechanism is thoroughly analyzed, with a detailed quantitative characterization of the dissipation capacities of polarization, conduction, and magnetic loss.
Inspired by DNA transcription, atom and geometry configurations co-modulating multi-scale helical converters achieve the RL_min of −63.13 dB at 1.29 mm, and the maximum RCS reduction value reach 36.4 dB m².
Orbital coupling, spin and cross polarization synergize to realize a 6.08 GHz EAB, further expanding to ultrabroad electromagnetic wave absorption of 12.16 GHz through metamaterial design.

为定制超宽电磁吸收设计多尺度螺旋转换器的电子结构

受 DNA 转录的启发，原子和几何构型共同调制的多尺度螺旋转换器在 1.29 mm 时的最小 RL 值为 -63.13 dB，最大 RCS 降低值达到 36.4 dB m2。轨道耦合、自旋和交叉极化协同实现了 6.08 GHz 的 EAB，并通过超材料设计进一步扩展到 12.16 GHz 的超宽电磁波吸收。

期刊介绍： Nano-Micro Letters is a peer-reviewed, international, interdisciplinary, and open-access journal published under the SpringerOpen brand. Nano-Micro Letters focuses on the science, experiments, engineering, technologies, and applications of nano- or microscale structures and systems in various fields such as physics, chemistry, biology, material science, and pharmacy.It also explores the expanding interfaces between these fields. Nano-Micro Letters particularly emphasizes the bottom-up approach in the length scale from nano to micro. This approach is crucial for achieving industrial applications in nanotechnology, as it involves the assembly, modification, and control of nanostructures on a microscale.
