Abstract:In recent years, electromagnetic (EM) wave absorbing devices based on metamaterials have attracted widespread attention from researchers around the world, due to their advantages such as broadband, easy preparation and flexibility to tailor EM waves. Nevertheless, a review of the existing research reveals that the inherent sub-wavelength characteristics of metamaterials and metasurfaces impose certain constraints on their use in low-frequency ranges. In order to achieve low detectability that takes into accoun… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
