Shielded structures are widely used today to perform various tasks ranging from providing EMC equipment and ending with the protection of information processed by the technical means located in such a shielded structure. At the same time, when a shielded structure performs the function of protecting information, it is important to understand how significant the influence on the signal propagation to the location of the alleged intruder is made not only by the shielded structure used, but also by other obstacles located on signal propagation path. The aim of the work is to develop a methodology for estimating the attenuation of the radio signal introduced by various obstacles, which are various previously known materials with known characteristics. The dependence of the effectiveness of screening, absorption and internal multiple reflection of electromagnetic waves on the type and characteristics of both conductors and dielectrics is considered.
Key words: : shield, shielded structure, shielding efficiency, radio signal, radio signal attenuation.
