Abstract
A waveguide device for producing absorption or attenuation includes a waveguide section which is provided with an external absorber material. For allowing a transfer of the high-frequency power into the absorber material, the wave section is provided with coupling apertures via which the absorber material is in connection with the interior of the waveguide section.
Claims18
A waveguide device for producing absorption or attenuation;
- comprising:
- a waveguide section defining an axis and having an interior;
- and
- absorbing means arranged externally along said waveguide section for absorbing or attenuating a wave propagating in said waveguide section in a direction of progation along said axis, said waveguide section being provided with a plurality of apertures for coupling said absorbing means with said interior, said apertures being spaced successively along the direction of wave propagation and being of a shape and dimension so that the wave is allowed to penetrate said absorbing means and a same amount of power is coupled out through each of said apertures.
