Dispersion of dielectric permittivity for composite material based on resistive dipoles

A correspondence has been established between the electrodynamic characteristics of a thin conductive cylindrical dipole and a needle-shaped ellipsoid. A well-known experimental result is theoretically justified, according to which an ellipsoid of the same material inscribed in it corresponds to a dipole. It is shown that, depending on the magnitude of the skin effect, the dispersion dependence of the effective dielectric constant of a dipole-based composite can correspond to both the Lorentz dielectric model and the Debye model. The results of calculating the dielectric constant of the composite according to various mixing formulas are compared with experimental data.
