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.
Claims11
A waveguide for electromagnetic waves;
- comprising:
- a tube having an inner wall lined with a coating of highly dissipative material and with a metallized layer along the inside of said coating, said metallized layer having a thickness continuously decreasing in direction of propagation of the waves through said tube from an initial thickness of a magnitude in correspondence with the penetration depth of the waves.
A waveguide for electromagnetic waves;
- comprising:
- a tube having an inner wall lined with a coating of highly dissipative material and with a metallized layer along the inside of said coating wherein said tube defines a center plane, said metallized layer having a first section of a thickness continuously decreasing towards said center plane in direction of propagation of the wave and a second section of a thickness continuously increasing from said center plane in propagating direction of the wave.
