Dielectric Loss Mechanism in Electromagnetic Wave Absorbing Materials

🤖 Plain-English Summary

Electromagnetic (EM) wave absorbing materials play an increasingly important role in modern society for their multi-functional in military stealth and incoming 5G smart era. Besides, in-depth dielectric loss study and novel dielectric loss mechanisms are emphasized.

🔑 Key Findings

• Dielectric loss EM wave absorbers and underlying loss mechanism investigation are of great significance to unveil EM wave attenuation behaviors of materials and guide novel dielectric loss materials design.
• However, current researches focus more on materials synthesis rather than in-depth mechanism study.
• Herein, comprehensive views toward dielectric loss mechanisms including interfacial polarization, dipolar polarization, conductive loss, and defect-induced polarization are provided.
