Abstract

PURPOSE:To secure a large amount of power for the fixed attenuation quantity regardless of the diameter of the using waveguide in terms of structure, by providing the coupling hole determined by the necessary attenuation quantity and the attenuation of the electromagnetic wave absorber to the wall of the waveguide and then attaching the absorber in a unit to the outer side of the waveguide.
