Abstract
Four composite nanofibers with specific concentrations of PVP and BiFeO3, GO, and SrFe12O19 reinforcements were synthesized separately, which were named G, S, B, GBS: G (PVP + GO), S (PVP + SrFe12O19), B (PVP + BiFeO3), and GBS (PVP + GO + BiFeO3 + SrFe12O19). The structural, magnetic, and dielectric properties of the composite successfully prepared by the electrospinning method were investigated to absorb electromagnetic waves in the frequency range of 8–12.5 GHz. Negative values observed in imaginary parts of permeability and permittivity in a large frequency range can be explained by new structures called left-handed. The maximum amount of reflection loss in the X-Band range around the frequency of 11.66 GHz for G, S, B, and GBS samples are obtained at −36.8, −37.66, −39.3, and −39.5 dB, respectively, which shows relatively good potential in military applications.
