Abstract
For damping undesired high frequency electromagnetic oscillations on HF technology components, such as coaxial lines, waveguides and resonators, as well as for the use in resonant circuits of VHF amplifiers with high HF power electron tubes, an absorber is proposed, which can be stablely coupled in mode-selective manner, while having a negligible influence on undesired low frequency and/or other electromagnetic oscillations, while having a predetermined high-pass characteristic. Absorber elements are used, which comprise a pocket made from a material having a high electrical conductivity with an opening on one longitudinal side and surrounding a ferritic, dielectric or ohmic absorber rod. For amplifying the absorption effect and for the predetermined setting of the absorption direction, a plurality of these absorber elements can be arranged with a predetermined geometry with respect to the component generating, transporting and/or emitting the HF power.
