Measurement of Electromagnetic Properties of Food Products and Liquids

Tomasz Karpisz , Bartłomiej Wacław Salski , Paweł Kopyt , Jerzy Krupka


In this paper, measurement results of electromagnetic properties of water and selected fruits and vegetables are presented. The applied method is based on a commercially available open-ended coaxial line operating at frequencies up to 27 GHz. Subsequently, a novel method dedicated to the characterization of liquids at frequencies substantially exceeding 27 GHz is proposed. The system is based on a vertically-oriented open-ended metal hollow waveguide, so that the liquid can be easily poured into and the corresponding reflection coefficient can be measured to determine unknown complex permittivity of the liquid
