Free space transmission loss measurement of magneto-dielectric materials: Solution uniqueness and measurement tolerance tradeoffs

The possibility to determine the specific conductivity, permittivity, and permeability of homogeneous magneto-dielectric materials by measuring it´s wideband transmission without measuring it´s reflection is investigated. Uniqueness of extracted material parameters along with its sensitivity to measurement tolerances are examined. The novel measurement approach for material samples exhibit very low loss within the test frequency band is introduced.
