Composite's dielectric permeability inclusive of its correlated structural function and Maxwell-Wagner relaxation

The specified analytical decision for the tensor of effective dielectric permeability of a composite with a disordered polydisperse structure in the form of decomposition through known decisions for basic structures and the specified coefficient of correlation is received. The correlation coefficient was obtained on the basis of the analysis of structures’ correlation functions. The calculation accuracy is illustrated on the example of calculation of effective dielectric permeability of the composite with disordered polydisperse structure. Numerical calculations and the influence analysis taking into account Maxwell-Wagner relaxation on the real and imaginary parts of effective dielectric permeability of the polymer/ferrite composite with various polydisperse structures filled up by different volumes of ferrite fibers and frequencies of enclosed electric fields are carried out.
