Design of ultra wideband microwave absorber effectual for objects of arbitrary shape

doi:10.1088/1674-1056/24/12/124101

Abstract In this paper, we present the design of multilayer microwave absorbers comprised of CoFe alloy nano-particles and nano-flakes as fillers. The thickness of the unite layer is optimized by using the Genetic Algorithm. Efficient microwave absorptions over a wide frequency band and a range of incident angles are achieved by using multilayer absorbers. We show that the absorbers are effective not only for a planar surface but also for arbitrarily shaped objects as well.

Keywords: multilayer absorber ultra wideband absorption genetic algorithm (GA)
