Transmission of EM Waves Passing Through a Multilayer Structure

This article investigates the behavior of an electromagnetic field passing through a composite material—a multilayered structure. The material consists of a dielectric material polymethyl methacrylate (acrylic, plexiglass) to which one or more layers of conductive paint are applied to attenuate the field strength. This field attenuation is possible precisely because of the chemical structure of the paint, which contains carbon-based particles and is therefore very successful in its purpose. Research was carried out with the stated aim—simulations and confirmation by measurements—to investigate the attenuation of the EM field when passing through a multi-layered structure.
