Graphene‐Based Materials toward Microwave and Terahertz Absorbing Stealth Technologies

Abstract Electromagnetic wave absorbing materials play an increasingly important role in consumer electronics and military defense. The remarkable merits of atomically thin graphene structures and their exotic optoelectronic properties provide new opportunities to design high‐performance electromagnetic wave absorbers. This progress report summarizes the recent advances in graphene‐based microwave and terahertz stealth materials. In the first section, the theory of electromagnetic wave absorption and the evaluation methods for absorption performance are briefly introduced. Then, representative graphene‐based microwave and terahertz absorber systems are presented with an emphasis on the selection of the absorbent component and structural design. In the last section, the perspectives and future research directions of this promising field are discussed.
