Abstract: Analyzing the absorption behavior of an object includes: generating at least one electromagnetic signal such that a fixed spatial electric field distribution is produced; modulating the electromagnetic signal with a waveform to generate a modulated signal which is emitted as a forward electromagnetic wave towards the object to be analyzed; measuring at least one wave quantity of the forward electromagnetic wave; receiving a backward electromagnetic wave; measuring at least one wave quantity of the backward electromagnetic wave; and evaluating the measured wave quantity of the backward electromagnetic wave and the measured wave quantity of the forward electromagnetic wave by respectively transforming the measured wave quantities to obtain a spectrum of the respective transformation, wherein the spectrum assigned to the forward electromagnetic wave is compared with the spectrum assigned to the backward electromagnetic wave to determine deviations of the spectra from each other based on which the object is chara

Abstract: A method for detecting an influence of microwaves on a measurement value of a temperature sensor of a core temperature probe of a cooking appliance, includes: recording the measurement value of the temperature sensor; determining the slope of the course of the recorded measurement values in at least one analysis interval (A, B) which is in a predetermined relation to a switch-on time and/or a switch-off time of a microwave generator; determining whether the slope lies above or below a predefined threshold; interpreting the exceedance of or falling below the threshold to the effect that the corresponding temperature sensor is not located in a food to be cooked and/or the core temperature probe is not correctly inserted into the food or into a receptacle provided for the same.

Abstract: An antenna configuration for a cooking appliance with a cooking chamber, including at least one accessory for introducing at least two cooking product carriers for the treatment of cooking products on at least two treatment levels. The accessory carrying multiple antennae. The cooking appliance having an equipment chamber or technical chamber separated from the cooking chamber having at least one microwave source, whereby the antennae are fed from the microwave source with microwaves with wavelength ? through a system of lines of the accessory. At least one antenna is arranged per treatment level and each treatment level is arranged in a resonant body for the microwaves. The resonant body defined by a cooking product carrier and the cooking chamber or between two cooking product carriers. The antennae comprise detuned ?/4 rods to provide essentially the same microwave energy to each treatment level.
