Abstract
The present disclosure relates to a metamaterial for converging electromagnetic waves, which comprises a plurality of cubic metamaterial units arranged in a first array which takes a y direction as a column direction and a z direction perpendicular to the y direction as a row direction. The metamaterial units of each row have the same refractive index, and for the metamaterial units of each column, the refractive indices thereof for the electromagnetic waves decrease gradually from a middle metamaterial unit towards two ends of the column, with variations of the refractive indices between adjacent ones of the metamaterial units increasing gradually from the middle metamaterial unit towards the two ends of the column; and the metamaterial units are anisotropic to the electromagnetic waves. The metamaterial for converging electromagnetic waves of the present disclosure can achieve the function of converging electromagnetic waves, and has a smaller thickness compared to conventional metamaterials.
