"Chaff is a military radar countermeasure consisting of small, metallic-coated silica fibers that are released in large quantities via aircraft or rockets to mask targets of interest to an enemy radar (Fig. 1; De Martino 2012). These fibers are cut to lengths that resonate at a desired frequency, meaning that chaff fibers are often cut on the order of centimeters (Hessemer 1961; Palermo and Bauer 1965)."
