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.
