Design of ultra wideband microwave absorber effectual for objects of arbitrary shape
CHINESE PHYSICS B(2015)
摘要
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.
