Dielectric Measurement Of Multi-Layered Medium Using An Open-Ended Waveguide
Published online by Cambridge University Press: 10 February 2011
Abstract
The use of a circular waveguide radiating into a multi-layered media allows the characterization of heterogeneous and fluid subtances. Many microwave measurement devices, based on reflection coefficient measurements, are subjected to air gap problems that introduce some inaccuracy in the determination of the unknown complex permittivity of the materials. Our purpose is to try and take the air gap into account in these measurements.
