Preparation of ferrite based nanostructure and investigation on electromagnetic properties

Camouflaging weapons, especially airplanes, helicopters, and drones, is inevitable. Radar camouflage means hiding a weapon from different types of radars that are done in a variety of ways that the reduction of the radar cross section or the use of radar absorbing materials are the most important methods [1-2]. In this research, Barium strontium hexaferrite nanostructure was synthesized by sol-gel method. The characterization of nanoparticles was performed by SEM, XRD, FTIR, and VSM analyzes. Absorption properties of the nanoparticles were investigated by Vector Network Analyzer at 8-12 GHz. The best absorbance was observed in -16 dB at the X-band range while the weight ratio of the powder was 20% and in 2 mm thickness
