The most pressing need for the majority of applications is the development of microwave absorption composites with thin thickness to make them practical to use and capable of high absorption with adjustable effective absorbing bandwidth. In this research, an innovative nanocomposite made of a LaFeO3 compound decorated with CuCo2O4 particles was chemically developed, and its electromagnetic properties were extracted to study microwave absorbing capability using both waveguide and free space methods, as well as related mechanisms. The resin-based absorber sample with 40% LaFeO3/CuCo2O4 nanocomposite possesses the best wave dissipation feature, with a reflection loss of 20 dB and an absorption bandwidth of 3.3 GHz in an absorber sample with just 1.8 mm thickness. This is due to the best loss capacity matching factor as well as improvements in impedance matching and attenuation coefficient capability.
