Comparative Study of the Electromagnetic Wave Absorption Properties in (FeNi, CoNi, and FeCo)/ZnS Nanocomposites

چکیده مقاله

Three EM wave absorbing (FeNi, CoNi, and FeCo)/ZnS nanocomposites were synthesized by simple and successful process. By comparison, it was demonstrated that the maximum attenuation constant as well as magnetic loss parameter corresponds to the prepared FeNi/ZnS nanocomposite. It resulted in an optimum reflection loss of - 26.5 dB at about 12.2 GHz with a thickness of 5.9 mm. Based on the experimental results, the electromagnetic wave absorbing in this synthesized nanocomposite was attributed to the eddy current loss factor.
