Abstract
Measurements of the real and the imaginary components of the complex dielectric permitivity for a ferrofluid consisting of magnetite particles surfacted with oleic acid, dispersed in kerosene, and for the ferrofluid constituents, in the frequency range of 100MHz - 6GHz are presented
The paper presents existing theoretical models regarding the dielectric properties of a binary dielectric mixture and, based on the experimental measurements, verifies the Maxwell - Garnet and the Gunther-Heinrich models for a ferrofluid considered to be a dielectric binary system.
