Interface-induced dual-pinning mechanism enhances low-frequency electromagnetic wave loss

Interface-induced dual-pinning mechanism enhances low-frequency electromagnetic wave loss Abstract Improving the absorption of electromagnetic waves at low-frequency bands (2-8 GHz) is crucial for the increasing electromagnetic (EM) pollution brought about by the innovation of the fifth generation (5G) communication technology. However, the poor impedance matching and intrinsic attenuation of material in low-frequency bands hinders the development of low-frequency electromagnetic wave absorbing...
