Described is an RF apparatus (100), comprising: - an RF resonance device (110) with an electrically conducting outer wall (111), wherein the outer wall (111) comprises a gap (114) extending along the extent thereof, and - a coupling-in device (130) with an RF generator (131), arranged on the outside (113) of the outer wall (111) of the RF resonance device (110) in the region of the gap (114), for coupling RF radiation of a specific frequency (fG) via the gap (114) into the inside of the RF resonance device (110), and a shield (134) which shields the generator (131) towards the outside and electrically bridges the gap (114) on the outside (113) of the outer wall (111), wherein the shield (134) is configured as a resonator having high impedance at the generator frequency (fG). |
