Abstract :
Ferromagnetic metal particles of thin-plate shape (whose thickness is controlled to be below skin depth) draw more attention for the industrial application to near-field noise absorbers in quasi-microwave frequency band. Experimental and theoretical studies have been done for demonstration of noise absorbing capability of those magnetic materials in the frequency region below 3 GHz. In this study, iron flake particles were chosen as the absorbent filler in rubber matrix and their noise absorbing characteristics was investigated as a function of frequency (0.5-10 GHz), sheet size covering the transmission line, and material parameters of the composite sheets.
