S-parameters of bismuth iron garnet (BIG) filled polyvinylidene fluoride composite using rectangular waveguide method
Nanosized Bismuth Iron Garnet (BIG) was synthesized via sol-gel method. The nanomaterials with ferrite structure were heat-treated at different temperatures from 700 to 1100 °C. The structure and morphology were characterized by Powder X-ray diffraction (PXRD). The PXRD show that with the increase...
