A resonator arrangement has a conductive, semi-open outer housing, at an interior of which a conductive bar is provided disposed coaxially to the housing. At one end of the bar in a direction of a housing bottom, the bar has a die and, together with a dielectric and the housing bottom, forms a capacitor. The bar is short-circuited to the housing at another end, so that the bar and housing together form an LC oscillator circuit. Also disclosed is a method for analyzing a sample using a resonator arrangement.

Resonator arrangement and method for analyzing a sample using the resonator arrangement

A method and apparatus for identifying a sample in a container, provide for the container with the sample being disposed relative to a resonator, a high-frequency signal being coupled into the resonator for exciting a resonant mode of the resonator, the resonant electric field of the resonator penetrating part of the sample in the container, the resonance curve of at least one resonant mode being measured with and without the sample, and the sample being identified based on the determined change in the resonance frequency compared to a measurement without sample.

Method for identifying a sample in a container, e.g. when conducting a traveler survey in the check-in area, by determining the resonance frequency and the quality of a dielectric resonator to which the container is arranged
