Graphene based structures and methods for broadband electromagnetic radiation absorption at the microwave and terahertz frequencies

摘要

Structures and methods for cloaking an object to electromagnetic radiation at the microwave and terahertz frequencies include disposing a plurality of graphene sheets about the object. Intermediate layers of a transparent dielectric material can be disposed between graphene sheets to optimize the performance. In other embodiments, the graphene can be formulated into a paint formulation or a fabric and applied to the object. The structures and methods absorb at least a portion of the electromagnetic radiation at the microwave and terabyte frequencies.
