Study of the parameters of conductive textile fabrics for protection against high-frequency electromagnetic radiation

There are various methods for shielding the electromagnetic radiation, but they are sometimes inapplicable due to the configuration of the premises, the location of the transmitters and receivers and the requirements of the operating equipment. A modern method to solve this problem is by using flexible screens made of fabrics impregnated with specific metals (conductive textile fabrics, metalized textile fabrics), which provide protection at different source configurations, frequency and signal strength. The aim of the work is a comparative analysis of the changes of the electromagnetic field parameters at standard household configurations (with different frequency) as EMF sources and shielded by protective factory-produced flexible screens. Two types of conductive textile fabrics have been tested (with silver and copper-nickel fibers) with two radio frequency sources. Comparison of the results with valid international standards has been also made. The corresponding conclusions regarding the shielding effectiveness of the two sample have been made.
