Transparent Radio-Shielding Materials Based on Multilayer and Mesh Structures

Abstract: Methods for fabrication of materials that simultaneously exhibit high transparency in the visible spectral range and radio shielding in a wide frequency band are considered. The main structures of such materials (multilayer coatings and mesh structures) are analyzed and compared, and several technological procedures are considered. It is shown that optimization of the thickness and chemical composition of multilayer coatings and geometrical parameters of mesh structures can significantly improve their properties. Promising structures are proposed to obtain an optical transmission coefficient of 90–98% and a radio shielding coefficient of 50–65 dB. © 2022, Pleiades Publishing, Inc.
