US Patent:
52085996, May 4, 1993
Filed:
Aug 28, 1991
Appl. No.:
7/751419

Chang-Fa Yang - Columbus OH
Assignee:
Ohio State University - Columbus OH
International Classification:
H01Q 1700
US Classification:
342 4
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.
