Abstract
A device for reflecting electromagnetic energy comprises a solidified foam mass which has reflector agents embedded therein for reflecting at least one frequency of electromagnetic energy. The frequency or frequencies of electromagnetic energy reflected are within the region of the electromagnetic spectrum utilized for radar signaling, the infrared region, the visual region or within any combination of those regions. A variety of dyes are used for reflecting frequencies within the infrared region of the electromagnetic spectrum and a variety of phosphorous compounds are utilized for reflecting frequencies within the infrared region of the electromagnetic spectrum. Radar energy is reflected by a multitude of discreet electrically conducting elements or dipoles of a length approximately equal to one-half (1/2) the wave length of the radar energy to be reflected which dipoles are distributed in an approximately uniform manner throughout the mass during the formation of the foam mass.
