In this work, the microwave absorption performance of barium hexaferrite multi-nanolayers synthesized by aceramic method was investigated. The microwave absorption performances of BaFe12 O19 and BaCoZnFe10 O19 multi-nanolayers with thicknesses of 25, 50, 75, 100, 200, 300, 500, and 1000 nm were evaluated using a vector network analyser (VNA) at room temperature to characterize the reflected signal (S11) and transmitted signal (S21) in the frequency range of 7–13 GHz. The microwave absorption performance of the multilayer structure was enhanced due to the combination of nanolayers. The optimal absorption performance was achieved with a reflection loss of less than −30 dB (99.9% absorption) for a layer thicknesses of less than 500 nm. © 2020 by American Scientific Publishers.
