Abstract :
A thin tapered absorber is described that is capable of effecting wide band absorption of electromagnetic waves at oblique incidence. The absorption mechanism for the taper is shown to be inherently wide band and seems not to be constrained by the bandwidth/reflectivity limitations that apply to thin planar materials. Predicted reflectivity data for the tapered absorbing layer are shown
