Electrodynamic analysis of nanocomposite microwave screening via equivalent RLC circuit models

Abstract

This study presents an electrodynamic analysis of hybrid nanocomposites consisting of carbon nanotubes (CNTs) with embedded ferromagnetic nanoparticles for microwave screening. By utilizing equivalent parallel and series RLC circuit models, we demonstrate that these materials offer a unique combination of broadband shielding and tunable resonance. Experimental parameters for resistance (R), capacitance (C), and inductance (L) were mapped to the physical morphology of the nanocomposite, revealing that the integration of magnetic nanoparticles significantly enhances the inductive response and absorption characteristics. Results indicate that while parallel networks provide stable broadband attenuation, series configurations enable frequency-selective screening, making these hybrids ideal for high-frequency applications in 5G/6G and aerospace sectors.
