    • Embodiments of the present invention relate to a chaff electronic countermeasure device for protecting mobile platforms against radio frequency threats. A device comprises an antenna that is in communication with a substrate. An integrated circuit is in electrical communication with the antenna. The device is configured to absorb from a source a first radio frequency having a first amplitude. In response to absorbing the first radio frequency, the device reradiates at least a portion of a second radio frequency having a second amplitude toward the radar source, which results in an increased radar cross section of the device as perceived by the radar source. The second amplitude is higher than the first amplitude.

    • An article comprising a non-conductive substrate having a sub-micron thickness of an oxidizable metal coating thereon, and at least one feature selected from the group consisting of: (i) an oxidation enhancingly effective amount of a salt, present on the oxidizable metal coating; (ii) a second (promoter) metal which is galvanically effective to promote the corrosion of the oxidizable metal coating, discontinuously coated on the oxidizable metal coating; (iii) the oxidizable metal coating being sulfurized; and (iv) the oxidizable metal coating being overcoated with a microporous layer of an electrically insulative material. Also disclosed are related methods of forming such articles, comprising chemical vapor depositing the oxidizable metal coating on the substrate. When utilized in a form comprising fine-diameter substrate elements such as glass or ceramic filaments, the resulting product may be usefully employed as an "evanescent" chaff. In the presence of atmospheric moisture, such evanescent chaff undergoes oxidization of the oxidizable metal coating, so that the radar signature of the chaff transiently decays.

    • An article (130) comprising a non-conductive substrate (136), preferably of an environmentally degradable character, having a thickness of an oxidizable metal coating (138) thereon, and optionally an oxidation enhancingly effective amount of a salt (140), e.g., from about 0.005 to about 25 % by weight of salt, based on the weight of oxidizable metal, present on the oxidizable metal coating. Also disclosed is a related method of forming such article, comprising chemical vapor depositing the oxidizable metal coating on the substrate. When utilized in a form comprising fine-diameter substrate elements such as filaments, the resulting product may be usefully employed as an "evanescent" chaff. In the presence of atmospheric moisture, such evanescent chaff undergoes oxidization of the oxidizable metal coating so that the conductivity and radar absorbance/reflectance characteristics of the chaff transiently decays. The chaff may be packaged for use in a cartridge (120) or the chaff may be provided by precursor roving packages (204) which are cut to the desired dipole length by a suitable cutter device (200) for dissemination to the locus of use.
