Describing Method for Information Protecting Composite Materials

Article Preview

Abstract:

For the purpose of discussing the potentiality of composite materials in information protecting, the microwave transmitting properties of epoxy-based carbonyl iron composite material was systematically analyzed in this report. The effective medium approximation (EMA) model was used to calculate the electro-magnetic parameters of the material, while the transmission line model was used to calculate the absorption ability of the composite material. Good agreement between calculation and experiments was obtained, which means the rationality of the describing method in this paper.
