Abstract. Influence of the thickness of a layer of polyethylene between unidirectional ferrite fibers and frequencies of electric field on effective dielectric permeability and conductivity of a polydisperse composite taking into account maksvell-wagner relaxation is investigated. Schedules of frequency dependences of effective constants and Cole-Cole's charts of the composite are provided. Not Debye character of a dielectric relaxation in polydisperse matrix structures is confirmed.

Key words: maxwell‑wagner relaxation, composite, effective properties, polydisperse structure.
