Abstract
A high-frequency-based measuring device for determining a dielectric constant of a medium comprises a signal-generating unit for coupling an electrical high-frequency signal into a transmitting electrode located in the medium, the transmitting electrode having a depth of at most one quarter of the wavelength of the high-frequency signal; a receiving electrode likewise located in the medium and located a distance from the transmitting electrode of at most one quarter of the wavelength of the high-frequency signal, for receiving the high-frequency signal after the same has passed through the medium; and an evaluation unit designed to determine the dielectric constant on the basis of the received high-frequency signal.
