Flexible metamaterial structure based on graphene structures

摘要

A flexible graphene-based metamaterial structure is disclosed that can operate at above liquid helium or liquid nitrogen temperatures, up to room temperature or above in applications similar to those for which a superconductor-based material structure is used. The flexible graphene-based metamaterial structure is formed from a flexible substrate, and a plurality of two-dimensional graphene blocks disposed in an array on the flexible substrate, each graphene block having a plurality of graphene sheets. The lateral dimension of the face of the graphene blocks is dependent on the temperature of operation of the flexible metamaterial structure. The flexible graphene-based metamaterial structure can be used for cloaking, with application in magnetic shielding.
