Abstract
Radar absorbent materials have been classically regarded as "resonant" when they are a quarter-wavelength thick. However, the actual thickness that minimizes the reflectance of a material is hardly ever a quarter-wavelength. If the material is dominantly magnetic in character, the required thickness for minimum reflection may even exceed a half-wavelength.
