The study investigates the impact of thickness on the electromagnetic interference (EMI) shielding effectiveness (SE) of Cobalt ferrite/ Graphene/ Epoxy (GrEpCoF) composite samples. Samples were prepared using a simple casting method. Cobalt ferrite was synthesized using hydrothermal method. The XRD of pure epoxy, graphene and cobalt ferrite is obtained. Microstructure of pristine epoxy and GrEp sample was studied using SEM. Further GrEpCoF with varying thickness was prepared. The impact of thickness on both the electric as well as the magnetic loss was studied for two bands, viz. X-band (8.2-12.4 GHZ) and Ku band (12.4-18) GHz. In addition, the EMI SE is also explored for these samples. © 2023 Elsevier Ltd. All rights reserved.
