The nanomaterials with ferrite structure were heat-treated at different temperatures from 500 to 1000 °C. The phase identification, morphology and functional groups of the prepared samples were characterized by powder X-ray diffraction (PXRD), scanning electron microscopy (SEM) and Fourier transform infrared spectroscopy (FT-IR), respectively. The YIG ferrite nanopowder was composited with polyvinylidene fluoride (PVDF) by a solution casting method. The magnitudes of reflection and transmission coefficients of PVDF/YIG containing 6, 10 and 13 YIG, respectively, were measured using rectangular waveguide in conjunction with a microwave vector network analyzer (VNA) in X-band frequencies. The results indicate that the presence of YIG in polymer composites causes an increase in reflection coefficient and decrease in transmission coefficient of the polymer. © 2012 by the authors; licensee MDPI, Basel, Switzerland. %D 2012 %R 10.3390/ijms13078540 %N 7 %O cited By 21 %L scholars3174 %J International Journal of Molecular Sciences %T Reflection and transmission coefficient of Yttrium iron garnet filled polyvinylidene fluoride composite using rectangular waveguide at microwave frequencies %I MDPI AG %A H.
