Abstract

This paper describes the comparison of absorbing characteristics of ferrite, graphite and carbon black, in the frequency band of 1.5 GHz to the 3 GHz. The substance is mixed in distinct proportions with synthetic enamel and applied on plates of EPS covered with aluminum paper (NRL arch technique) and without covering (insertion between antennas technique). The experimental results show that the graphite presents the largest attenuation for the electromagnetic radiation in the in the frequency band analyzed.
