Various constituent ratios with 50:30, 40:40 and 30:50 wt % of U-type barium hexaferrite (Ba₄Co₂Fe₃₆O₆₀) and Gamma iron oxide (γ Fe₂O₃) have been used to designing the radar absorbing composites within epoxy resin system. In the current work, studies are done on electromagnetic and absorbing properties of γ Fe₂O₃ powder dispersed Ba₄Co₂Fe₃₆O₆₀-epoxy composites. X-Ray Diffraction (XRD), Field Emission Scanning Electron Microscope (FESEM) and Vibrating Sample Magnetometer (VSM) tools have been used for structural, surface morphology and magnetic properties respectively of the synthesized powder and fabricated composites. The electromagnetic properties (ε′, ε", μ' & μ") of fabricated composites were retrieved from measured reflection (S₁₁ & S₂₂) and transmission (S₁₂ & S₂₁) parameters in 2–18 GHz frequency range. Experimental finding show that the fabricated composite having 50 wt % of γ Fe₂O₃ of designed Ba₄Co₂Fe₃₆O₆₀/γ Fe₂O₃-epoxy composites possesses maximum absorption of 98.8% (RL_min of −19.89 dB) at 13.2 GHz for sample thickness of 3.2 mm. The fabricated microwave absorbers confirm the effective absorption performance which has potential for strategic applications and stealth technology.
