Designing Electronic Structures of Multiscale Helical Converters for Tailored Ultrabroad Electromagnetic Absorption

Nano-Micro Letters, Journal Year: 2024, Volume and Issue: 17(1)

Published: Sept. 26, 2024

Abstract Atomic-scale doping strategies and structure design play pivotal roles in tailoring the electronic physicochemical property of electromagnetic wave absorption (EMWA) materials. However, relationship between configuration (EM) loss mechanism has remained elusive. Herein, drawing inspiration from DNA transcription process, we report successful synthesis novel situ Mn/N co-doped helical carbon nanotubes with ultrabroad EMWA capability. Theoretical calculation EM simulation confirm that orbital coupling spin polarization Mn–N 4 –C configuration, along cross generated by structure, endow converters enhanced loss. As a result, HMC-8 demonstrates outstanding performance, achieving minimum reflection −63.13 dB at an ultralow thickness 1.29 mm. Through precise tuning graphite domain size, HMC-7 achieves effective bandwidth (EAB) 6.08 GHz 2.02 mm thickness. Furthermore, constructing macroscale gradient metamaterials enables ultrabroadband EAB 12.16 only 5.00 mm, maximum radar section reduction value reaching 36.4 m 2 . This innovative approach not advances understanding metal–nonmetal co-doping but also realizes broadband EMWA, thus contributing to development mechanisms applications.
