"electromagnetic wave pollution overcome using heterogeneous absorbing materials, whose structure formed by hard/ soft magnetic materials producing interfacial exchange coupling at heterogeneous interface, but insufficient heterointerface/ impedance mismatch and lack of good exchange coupling strength... overcome using 2D Fe3C/ZnFe2O4/C exhibiting wide 4.56 GHz EAB, -65.6 dB RLmin value... layer-to-layer stacking/ reduced graphene oxide enables effective 5G shielding in the form of flexible film"
