ABSTRACT:
A harmonic converting or generating material, particularly adapted for use as chaff in decoy rounds, and a method of fabricating the same. The material is formed from metallic foil to have the characteristics of a dipole and which by the addition to the midpoint thereof of semiconductor or other polarizable material has the capability of reradiating incident frequencies along with radiating harmonics thereof or undesirable noise. Thus, the passive material, when activated by an active source, such as a radar unit, serves to convert or generate spurious frequencies, harmonics and noise, in addition to reradiating the fundamental frequency of the active energy source, thus giving the illusion of a plurality of independent energy sources.
