    摘要: A radar absorber, for use as a sprayable paint, or for use as a plastic sheet, is provided. The radar absorber is used to cover a structural part of an aircraft or to shield a part of a naval vessel. The absorber, or coating in this embodiment, includes an inner layer having an elastomeric carrier material with a carbonyl iron powder dispersed therein, or disposed therein, of a regular particle size of about 4 to 5 micron, and includes an outer layer having an elastomeric carrier material with a carbonyl iron powder dispersed therein, or disposed therein, of a fine particle size of about 0.5 to 1.5 micron.
