Epoxy/filler particles (NiFe2O4 and BaTiO3) composites were prepared with 85/15 mixture ratios via Ultrasonic Probe Sonicator method in solution. The complex permittivity (e '-e '') and permeability (mu '-mu '') of the composites have been measured at different microwave frequencies in 1-14 GHz via vector network analyzer (Keysight N9926A). The reflection loss (R-L) of composites was calculated and evaluated from camplex permitivity and permeability. The obtained results show that both composites exhibit the large R-L and broadband within the frequency range from 1 to 14 GHz for different thickness. Epoxy/BaTiO3 showed a better microwave absorption at the range of 6-7.2 GHz for 7 and 6 mm, at the range of 7.4-9.1 GHz for 5 mm. However, the Epoxy/NiFe2O4 exhibits the largest R-L and the widest bandwidth than those obtained from Epoxy/BaTiO3 composite. POLYM. COMPOS., 39:E2143-E2148, 2018.
