Abstract:
1. A flexible metamaterial structure comprising: a flexible substrate; and a plurality of two-dimensional graphene blocks disposed in an array on, or embedded in, the flexible substrate, wherein each graphene block comprises a plurality of graphene sheets, wherein a minimum lateral dimension (l) of the face of the graphene blocks is dependent on the temperature (T) of operation of the flexible metamaterial structure, wherein the flexible metamaterial structure is a two-dimensional structure having a first side and a second side opposite to the first side, wherein the metamaterial structure exhibits a magnetic shielding effect of a component of a magnetic field that is applied to the first side of the flexible metamaterial structure, and wherein the magnetic shielding effect reduces the magnitude, on the second side of the flexible metamaterial structure, of the component of the magnetic field that is directed perpendicular to the first side of the flexible metamaterial structure; and wherein the graphene blocks are spaced apart in the array and wherein said spacing is by a distance of one of: about 10 microns or less, about 30 microns, about 50 microns or more, and between about 10 microns and about 50 microns.
