X-Band Electromagnetic Characterization of Fe₇₂Al₂₃V₅ Based Nanocomposites

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 S_ij 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.
