Description

technical field [0001] The present application belongs to the technical field of metamaterials, and in particular relates to a method and device for regulating an incident wave based on a metamaterial waveguide array. Background technique [0002] Metamaterials are artificial materials with sub-wavelength dimensions that possess properties and parameters that are not found in natural materials. In recent years, both electromagnetic waves and acoustic metamaterials have been greatly developed, especially the structured two-dimensional metamaterials have introduced super large, zero, anisotropic or negative refractive index parameters at the equivalent medium level, and have been applied It is used to manipulate sound waves to generate new physical phenomena and to develop a variety of new devices. For example, incident waves can be regulated through metamaterial waveguide arrays. [0003] In order to change the functional effect of the waveguide array, it can be realized by ...
