Electromagnetic wave absorption by an organic resin solution based on ferrite particles with a spinel crystal structure

摘要

We have investigated an organic resin solution designed for EM wave absorption based on a magnetic filler, composed of phases within the Mn_(0.66)Zn_(0.27)Fe_(2.07)O_4 system, embedded in an absorber composite with concentration ratios of 50:50, 75:25 and 90:10 by weight. The formation of the manganese zinc ferrite particles, as the principal magnetic phases, was achieved via the conventional ceramic method. The electromagnetic parameters of the composites were measured with a vector network analyser at 100 MHz to 10 GHz. The subject of the paper was a study of the electromagnetic absorber properties and the rheological properties of the resin composite based on ferrite particles with respect to using the materials in architectural coatings.
