Abstract. Numerical calculation and the analysis of influence of makswell-wagner
relaxation on the real and imaginary parts of effective electromagnetic factor of
polydisperse piezocomposites: PVF/ferrite with ellipsoidal ferrite inclusions,
layers and fibers of size of filling, a form of inclusions in variation
electric field is carried out. The effect of significant increase in
longitudinal effective electromagnetic factor for a composite with unidirectional needle ferrite inclusions in comparison
with similar coefficient for unidirectional fibrous or layered composites is
revealed.
