Abstract

A resonator unit includes a resonator chamber with a first opening for receiving container in a predefined position and for heating the container with microwaves coupled into the resonator chamber. The chamber has a second opening via which the microwaves are coupled into the resonator chamber, wherein the geometry of the resonator chamber relative to the predefined position of the container in the first opening is adapted by a device for adapting the geometry so that an electric field produced in the resonator chamber in a working mode is symmetrical in relation to the container or the impedance of the resonator unit equipped with container is approximately constant for containers of different configurations.
