DEVICE HAVING A RESONANT CIRCUIT, USE OF SUCH A DEVICE IN A RADIATION FIELD AND METHOD FOR OPERATING SUCH A DEVICE IN A RADIATION FIELD

摘要

A device (100) having a resonant circuit that can be excited by means of an alternating signal source (G). The resonant circuit comprises a non-linear switching element (10), and the device (100) is designed such that the non-linear switching element (10) can be operated in a non-linear working range and at a frequency above a threshold frequency.
