Abstract :
In this paper, the authors analyse the usefulness of a new composite absorbing material which can be used to make two-layer hybrid absorbers incorporating a ferrite base layer, using the method of homogenization and the transmission line approach. The results acquired show the possibility of obtaining a reflectivity in the range -20 dB and better in the frequency-range from around 30 MHz up to several GHz, using a thickness of absorber significantly less than that which is used with current types of absorbers given in this document.
