Abstract

This paper presents a concept for level monitoring of layered fillings in vessels with partially or completely unknown properties of the filling materials. A key sensor component is a composite right/left-handed transmission line resonator. Based on this element in combination with the multi resonant cavity perturbation theory an algorithm for the sensor signal processing is derived for the extraction of material properties and filling levels. The presented concept is verified with full wave electromagnetic simulations and experiments that had been carried out with a realized demonstrator.
