N2 - The fabrication of FeWO4/BiVO4 composites is a key initial step in the development of effective microwave absorber fillers. Tweaking the loading ratio of composites, complex permittivity and complex permeability of walnut-shaped FeWO4/BiVO4 microspheres is significantly improved. In addition, best sample displays a reasonable minimal reflection loss (RLmini) value, and its effective absorption bandwidth (EAB, with RL -10 dB) value is 3.6 GHz. Moreover, the best samples were evaluated via free-space testing technique too, and comparison is made between the waveguide and free-space measurements. Evidence suggests that the free-space approach can be a valuable additional testing strategy due to its touch-free and non-destructive characteristics. The ability to fabricate high-quality FeWO4/BiVO4 samples with adjustable characteristics and an alternate measurement procedure opens the door to promising novel microwave absorbers. As a result, FeWO4/BiVO4 is predicted to be an exceptionally efficient microwave absorbent material.
