Abstract

The invention discloses a piece of a dielectric waveguide or dielectrically filled metal waveguide which is used as microwave resonator in a sensor system to determine the properties of the material and the dimensions of the space surrounding the resonator. The resonator generates evanescent fields in this material and a space through a dielectric interface (2). The properties of the material and the dimensions of the space are determined indirectly by measuring frequency and band width of the transmission response of the resonator.
