Fabrication and characterization of Fe2O3-OPEFB-PTFE nanocomposites for microwave shielding applications

The development of microwave shielding nanocomposites based on recycled hematite nanoparticles, oil palm empty fruit bunch (OPEFB), and polytetrafluoroethylene (PTFE) was the main focus of this study. The complex permeability (μ′–jμ″), complex permittivity (ε′–jε″), reflection coefficient (S11), and...
