A COMSOL Study on the Effectiveness of Shielding in Composites Containing HDPE and Aluminium Nanoparticles

Abstract

In this study, we investigate the shielding efficiency (SE) of HDPE composites containing aluminum nanoparticles against electromagnetic interference (EMI). We try to calculate the SE between 8 and 12 GHz using the modeling and simulation tool COMSOL Multiphysics. This study aims to provide a detailed description of the shielding efficacy of an aluminum nanoparticle composite that might be used in future communication and electrical devices. The results show that the SE fluctuates significantly with frequency and that there are certain GHz bands with the lowest SE. These findings might help refine materials for GHz-range electromagnetic interference shielding.
