Screens for Protection Against Electromagnetic Radiation

Abstract

This paper presents the ways to protect workers against the electromagnetic fields in the radio frequency range up to one centimeter using a shielding method. The study focuses on the protective shields for absorbing that are produced from pure sheet metal using carbon filler between the metal sheets. There are compared their characteristics at the frequency range up to one centimeter that were obtained by calculations, modeling and experimental methods. Here are provided calculation formulas, results from computer modeling, experimental results from the metal shield itself and the shield with the carbon black filler. The results are presented in graphs. Comparison analysis of the absorption characteristics was done using a method that measured a signal that was reflected from the shield..
