Multi-phase measurements of structure by microwave waveguide methods

The possibility of simultaneous determination of parameters from the temperature dependence of the reflection spectrum of microwave (microwave) radiation for magnetic fluids and silicon. The dielectric constant, the volume fraction of the solid phase, the tangent of the dielectric loss angle, and the diameter of the magnetic fluid particles, and the thickness silicon sample, conductivity , effective mass, the activation energy and concentration boron in silicon are determined. It is shown that taking into account the dimensions and spatial arrangement of agglomerates from magnetite nanoparticles for magnetic fluids and temperature dependence concentration and mobility under the influence of two mechanisms of dispersion leads to an increase in the accuracy in determining the required parameters.
