ENHANCED CHARACTERIZATION OF DIELECTRIC PROPERTIES

摘要

A sensor for sensing a reflection or transmission property of a material, the sensor comprising an electromagnetic radiation input means for creating or receiving an electromagnetic radiation signal, a resonator for influencing the electromagnetic radiation input signal, a material holder for holding the material under test, a delay line positioned between the resonator and the material holder such that the electromagnetic radiation travels in the delay line after passing the resonator and prior to reaching the material under test, when it is positioned in the material holder, and a detection means for detecting a signal reflected by or transmitted through the material under test.
