Electromagnetic loss in carbon based materials

Electromagnetic loss in carbon based materials

Paper presents the results of investigation of electromagnetic insertion loss (A) for carbon materials, including thermoexfoliated graphite (TEG), TEG-metal and TEG-epoxy composites (CMs) in temperature ranges 77-300 K at the frequency f≈1.8 GHz. The performed investigations have shown that TEG-base...
