Abstract

The invention provides a metamaterial with a dielectric substrate with nonuniform thickness, which comprises a multilayer dielectric substrate and multiple artificial microstructures, wherein the multiple artificial microstructures are arranged on the dielectric substrate; and the metamaterial is characterized in that the thickness of the dielectric substrate is distributed nonuniformly. The metamaterial disclosed by the invention has the advantages that through designing the thickness of the dielectric substrate into a nonuniformly-distributed mode, the metamaterial has more abundant function applications; and as a concrete implementation mode of the metamaterial disclosed by the invention, the convergence, divergence and deflection effects of the metamaterial on electromagnetic waves can be achieved through the nonuniform distribution of the thickness, so that the metamaterial is simpler in process design and lower in production cost.
