The shielding electromagnetic (EM) waves is a very important field of the electronics, telecommunications and IT industries. The phenomenon of electromagnetic interference (EMI) can be a source of interference in electronic systems, which can both disrupt the operation of systems and provide a breach to intercept the flow of classified information. Hence, it is necessary to shield electronic and IT systems to prevent the coupling of circuits and prevent the monitoring of data emitted in the form of electromagnetic waves. An additional threat resulting from the EMI phenomenon is the possibility of inducing high voltages and currents in circuits that may temporarily or permanently damage electronic systems as a result of high-power electromagnetic pulses. Examples of sources of high-power impulses can be, for example, atmospheric discharges, gasoline engine ignition systems, electrostatic discharges, solar discharges, cosmic rays and military hardware, such as electromagnetic directed energy weapons. The paper will present the results of research carried out as part of interdisciplinary projects related to security threats to ICT systems in the area of critical infrastructure.
