Abstract

The investigation of metasurfaces presents an innovative method for attaining multi-band electromagnetic wave concealment. Presently, there exist two primary categories of multi-band stealth metasurfaces: those suitable for infrared and microwave frequencies and those appropriate for terahertz and microwave frequencies. Nonetheless, investigations into metasurfaces that concurrently offer stealth across the infrared, microwave, and terahertz spectra remain insufficient. This article presents a stealth metasurface suitable for infrared, microwave, and terahertz frequencies. The compatible stealth metasurface (CSM) may attain over 90 % cross-band absorption throughout the frequency ranges of 17.1 GHz–20.8 GHz and 2.04 THz-2.89 THz while exhibiting a low infrared emissivity (IE) of 0.46. This CSM uses the gradient principle to make absorption units of different sizes on its surface. To achieve cross-band absorption, it also uses a frequency-selective surface (FSS) as the reflecting layer, which is a first. Furthermore, the CSM's exterior is coated with low-IE materials, facilitating infrared stealth capabilities. The CSM's stealth properties across three electromagnetic wave bands make it very useful for military purposes, and the new way that FSS is used as a reflecting layer opens up a whole new way to make stealth metasurfaces that work with each other.

期刊介绍： Composites Communications (Compos. Commun.) is a peer-reviewed journal publishing short communications and letters on the latest advances in composites science and technology. With a rapid review and publication process, its goal is to disseminate new knowledge promptly within the composites community. The journal welcomes manuscripts presenting creative concepts and new findings in design, state-of-the-art approaches in processing, synthesis, characterization, and mechanics modeling. In addition to traditional fiber-/particulate-reinforced engineering composites, it encourages submissions on composites with exceptional physical, mechanical, and fracture properties, as well as those with unique functions and significant application potential. This includes biomimetic and bio-inspired composites for biomedical applications, functional nano-composites for thermal management and energy applications, and composites designed for extreme service environments.
