The Electrodynamic Properties of Fiber Composites

摘要: In this paper, calculations are carried out of the effective dielectric permeability tensor \( \left( {\mathop {\widetilde\varepsilon }\limits^ \wedge } \right) \) fiber composites which consist long conducted fibers embedded in a continuous matrix. We expect that each is made bulk “direct” short segments we allow to be thin bars with an average length 1 << λ (wave electromagnetic radiation medium). approximation medium (EMA), expressions for \widetilde\varepsilon case chaotic orientation fibers, as well as, dominated at any direction, obtained. It considered frequency dependence \right)\left( \omega condition has Drude’s character different ranges. treat behavior near percolation transition margins large volume fraction values fraction. This method calculation can easily generalized include thermal properties similar composites.
