A comparative analysis of composite materials for electromagnetic shielding efficiency in nanoelectronics

Abstract

Recent advancements in nanoelectronics have necessitated a critical evaluation of materials used for electromagnetic shielding (EMI) in integrated circuits. While conventional metals and polymers have been examined, their effectiveness has shown limitations in miniaturized applications. This study employs a multi-faceted experimental approach, integrating both quantitative and qualitative analyses, to compare the shielding efficiency of novel composite materials. A series of controlled experiments were conducted using both time-domain and frequency-domain methods. Our findings demonstrate that the developed composites exhibit shielding effectiveness (SE) enhancements ranging from 12-34 dB compared to traditional materials, specifically under frequencies exceeding 5 GHz. This work not only highlights the potential for improved performance in nanoelectronic devices but also proposes a new framework for material selection based on structural and electromagnetic properties.
