Shielding Effectiveness of Electromagnetic Field by Specially Developed Shielding Coating

Abstract

This article aims to present the results of the measurements of the electromagnetic wave penetration through the building element with a specially developed shielding coating. Shielding coating represents dispersed powder in semiconducting liquid. The powder consists of the complex oxides of La0.7Sr0.3MnO3 (LSMO), ZnFe2O4, NiFe2O4 composition and were prepared by self-combustion method using corresponding metal nitrates in required molar ratio and glycine as fuel. Measurements were made for powder concentration of 5 g. Measurements were performed in the frequency range from 0.8 GHz to 8 GHz. The measurement results show the electromagnetic wave shielding effectiveness of the used shielding coating.
