Electromagnetic Shielding using Graphene Material in Wide Bandwidth of 1.5GHz-10GHz

We report pristine graphene (pG) as an effective shielding material for electromagnetic interference (EMI) in electronics, and RF sensor systems. The pG was produced via a simple process of mechanical exfoliation of natural graphite. The performance of as-prepared graphene film coating alone with a thickness of 27.9 mu m.was evaluated in terms of shielding effectiveness (SE) and demonstrate SE similar to 22.7dB-16.7dB in 1.5GHz-10GHz frequency band. The insertion loss through the alumina substrate was subtracted from the measurement result.

Automated summary

This study reports the effectiveness of pristine graphene as a shielding material for electromagnetic interference in electronics and RF sensor systems. Pristine graphene with a thickness of 27.9 μm was produced through mechanical exfoliation of natural graphite, and its shielding effectiveness was evaluated through measurements.
