A method and device for operating an x-ray device including an x-ray emitter and an x-ray detector are provided. An alternating magnetic field is produced and emitted at the x-ray emitter. At least two sensors are included for capturing at least one physical variable correlating with the alternating magnetic field. An alignment of the x-ray detector relative to the x-ray emitter is determined based on the measurement.

The invention relates to a sensor () for determining a dielectric property of a medium (). The sensor () has a substrate (), which has at least one via (), and a waveguide (), which is arranged so as to be planar in relation to an upper surface of the substrate (). The waveguide () can be connected to an analysis device () by means of the at least one via (). Furthermore, the waveguide () is designed to receive an input signal from the analysis device () and to output an output signal to the analysis device (). When of the waveguide () is in contact with a medium (), properties of the input signal and of the output signal are indicative of the dielectric property of the medium (). The arrangement of the waveguide () so as to be planar in relation to the substrate () enables larger measurement ranges and improved measurement accuracies. Furthermore, a compact construction is achieved by the planar structure. The invention further relates to a sensor arrangement and a method for determining a dielectric property of a medium by means of a sensor.
