Abstract

The possibility of simultaneously determining four parameters of a ferrofluid (permittivity, the volume fraction of solid phase, loss tangent, and the diameter of ferrofluid particles) based on the temperature dependence of microwave reflection spectrum has been investigated. It has been shown that taking the dimensions and spatial arrangement of magnetite-nanoparticle agglomerates into account improves the accuracy of determining the parameters.
