Abstract
A waveguide usable as absorber or as attenuator for high radio-frequency powers up to highest frequencies includes a tube with a dissipative material at whose inside a metallized layer is applied. The thickness of the metallized layer changes along the length of the tube with its initial thickness and end thickness determined in such a manner that a constant power density is obtained along the waveguide.
