Abstract
Determination of the electromagnetic parameters is an important tool to evaluate the microwave-absorbing characteristic of a novel material. In this context, our research was carried out to investigate the electromagnetic parameters of nanocomposites samples obtained by inclusion of nanostructured Fe72Al23V5 powders in a resin matrix. Nanostructured Fe72Al23V5 powders were synthesized by high-energy mechanical alloying (MA) route and characterized using a scanning electron microscopy (SEM). The nanostructured Fe72Al23V5 powders were dispersed in an epoxy resin matrix. Nanocomposites bulk samples of rectangular section and given thickness were shaped for electromagnetic characterization in an X-band metallic rectangular waveguide. Electromagnetic characterization was performed in terms of measured Sij scattering parameters. Dielectric permittivity and magnetic permeability spectra were extracted over the microwave X-band via the transmission/reflection technique. Obtained results exhibit how the nature and size of the inclusions affect the electromagnetic parameters in the X-band frequencies.
