FIELD: assessment of complex dielectric constant and magnetic permeability of radio- absorbing materials. SUBSTANCE: circular samples are exposed to UHF-signal, and a measurement of the reflection factor module is taken. The value of the reflection factor module is determined as dependent on the sample thickness, and depending on the kind of this correlation the values of magnetic permeability and dielectric constant of the sample are assessed. EFFECT: simpler method. 3 dwg
