Thin radar absorber using artificial magnetic ground plane

Experimental verification is provided of the radar absorbing properties of an ultra-thin radar absorber. The absorber uses a commercially available conductive textile material uniformly coated with doped conducting polymer. The material is placed at a height of 0.12 lambda above a 4.6 GHz artificial magnetic ground plane. It is shown that with this arrangement better than -18 dB reflection loss can be obtained at 4.42 GHz.
