Sodium citrate-induced generation of multi-interfacial embroidered spherical SnO2for augmented electromagnetic wave absorption

In this paper, sodium citrate was selected as a shape inducer to construct a multi-interface embroidered spherical structure. The RL min value is −45.6 dB and the EAB at 2.6 mm is 6.08 GHz, owing to the mutual balance of impedance and attenuation.
