Special Issue Information

Dear Colleagues,

Owing to the rapid development of electronic technology, electromagnetic (EM) interference has emerged a significant and growing concern in today’s environment. Explosive EM waves harmfully affect both device performance and human health, and advanced EM wave detection technology also threatens national defense securities. Therefore, high-performance EM wave-absorbing materials are urgently required for both civilian and military applications. To satisfy the increasing requirement, various advanced materials have been explored with the support from fields of nanotechnology, material chemistry, and polymer science, among others. Nanomaterials exhibit remarkable advantages in the field of electromagnetic wave absorption due to their unique physical and chemical properties, such as highly specific surface area, quantum size effects, and interfacial effects. Currently, carbon-based nanomaterials, magnetic nanomaterials, and conductive polymer nanomaterials are widely studied and applied in wave-absorbing materials.

The present Special Issue of Nanomaterials aims to present the current state-of-the-art characterization of nanostructures, nanomaterial processing technology, and properties of novel nanomaterials for electromagnetic wave-absorbing materials, electronic functional components, and magnetic functional materials. Original research papers, communications, and review articles are welcome.

Terahertz waves have great potential for applications in security imaging, wireless communication, and other fields, but efficient and tunable terahertz-absorbing devices are the key to their technological development. In this paper, a tunable terahertz metamaterial based on graphene and vanadium dioxide materials is proposed. When the vanadium dioxide conductivity is 1.6 × 105 S/m and the Fermi energy level of graphene is 0.75 eV, the metamaterial exhibits high absorptivity exceeding 90% in ultra-broadband of 2.05–14.03 THz; when the Fermi energy level of graphene is adjusted to 0 eV, the high absorption wavelength range narrowed to 4.07–13.80 THz; when the vanadium dioxide conductivity is adjusted to 200 S/m, the metamaterial exhibits high transmissivity exceeding 80% in the wavelength range up to 15 THz. Additionally, the metamaterial is insensitive to polarization angles and incident angles, allowing it to adapt to changes in the angle of incidence and polarization in practical applications. The metamaterial has potential applications in optical switches, electromagnetic wave stealth devices, and filtering devices. Full article
