Abstract
Electromagnetic absorber having serrations on a surface or surfaces thereof to reduce reflectivity of incident electromagnetic waves thereon. The serrations form a plurality of fins, the height of adjacent fins being spaced by a small distance. Preferably the total absorber wedge height is greater than about 1 wavelength at the lowest design frequency and the height between the serration tips is less than 1/4 wavelength at the lowest design frequency.
