This paper presents the measurement technique that allows to determine the relative permittivity and permeability of powdered materials. Measurements are realized in a coaxial transmission line which guarantees the broad band frequency characterization. Calculations utilize the scattering matrix parameters of the two-port formed by the sample of powdered material supported by two dielectric walls. The proposed measurement procedure is demonstrated in the example of ferrite powder – Yiitrium Garnet YIG class ferrite for which the relative permittivity (ε′,ε″)(ε′,ε″) and permeability (μ′,μ″)(μ′,μ″) are determined in the frequency range of 200–1200 MHz.
► We investigated powdered Yiitrium Garnet ferrite.
► The explicit determination of scattering parameters of powdered sample.
► Proposed attempt to solve a multivalued logarithm.
► Values of relative complex permittivity and permeability in frequency range from 200 MHz to 1200 MHz.
