ABSTRACT = {This study investigated and defined the optimal processing parameters for the electrospinning of polysulfone polymer solutions with N,N-dimethylacetamide. Variation of parameters such as solute concentration, electrical voltage, and working distance were correlated with the quality of the obtained nanofibers using morphological characterization via scanning electron microscopy (SEM). Carbonyl iron additive was dispersed in the polymer solutions, using ultrasonic tip, and the material processed via electrospinning with aforementioned parameters defined. Nanofibers with the property of interaction with electromagnetic waves were obtained. The dispersion of different concentrations of the additive and electromagnetic characterizations in the X-band of microwaves (8.2 and 12.4 GHz), using vector network analyzer (VNA) and rectangular waveguide, allowed the identification of the materials electromagnetic behaviors. Scattering parameters allowed the calculation of reflected and transmitted energy by the material.},
