چکیده انگلیسی
Cobalt doped M-type strontium hexaferrite nanoparticles (SrCoxFe12-xO19, x = 0.2-1.2) is synthesized and used as inclusions in Linear Low Density Polyethylene (LLDPE) matrix for developing nano-composites with 60 wt% of these nanoparticles. Absorption performance of the developed nano-composites is evaluated in the X-band. The thickness optimization is carried out for obtaining maximum reflection loss by using the transmission line model (TLM), with measured values of permittivity and permeability of the composite. The best reflection loss is observed experimentally for x = 0.8 with an absorber thickness of 3 mm for which a wide â10 dB bandwidth covering almost the entire X-band is obtained. The composites are light weight and not affected by exposure to water.
