Microwave Absorption Using Multidimensional Co/BFO Nanocomposite

In this work, the multidimensional Cobalt/Barium Ferrite (Co/BFO) nanocomposite's microwave absorption properties are investigated. Using an efficient ball milling process, the nanocomposite was made by mixing 0D barium ferrite nanoparticles, 2D cobalt flakes, and 3D spherical cobalt particles. XRD, FESEM, and VSM studies were used to examine the nanocomposite's crystal structure, shape, and magnetic characteristics. The coaxial transmission-reflection technique was used to determine the microwave absorption parameters across the frequency range of 2 to 14 GHz. With a coating thickness of 2.0 mm, the Co15h+ BFO14 % sample displayed an improved absorption bandwidth of 4.2 GHz (4.8-9). The composite's multidimensional morphology increases interfacial polarization, numerous scattering, and reflection processes, resulting in increased microwave absorption efficiency. Because of its capacity to tune microwave absorption, the nanocomposite is a potential candidate for applications in telecommunications, military, and radar systems, where effective microwave energy absorption is critical.
