METAMATERIAL

摘要

A metamaterial, comprising a single metamaterial layer, wherein the single metamaterial layer comprises a dielectric substrate (3), a conductive geometry layer (4) attached to the dielectric substrate (3), and at least one through hole unit penetrating through the conductive geometry layer (4), wherein the through hole unit comprises two through holes (1, 2, 5, 6, 7, 8) of different sizes arranged in parallel in a two-dimensional direction of a plane, and centres of all through holes (1, 2, 5, 6, 7, 8) are arranged at equal intervals. By adjusting structure parameters of microstructures by coupling and superposing different microstructures, the metamaterial achieves multi resonance or wide resonance within a Terahertz range; and meanwhile, the metamaterial composed of the single metamaterial layer has the advantages of being light in weight, low in cost and easy to process, can save costs compared with the design of a multilayer material, thereby effectively solving the problems in the prior art that it is difficult to process a Terahertz device and the costs are high, and has an actual application value.
