Abstract

The invention discloses an electromagnetic code basic unit with a self-adaptive function and a metamaterial. The metamaterial comprises N*N 2-bit programmable coding units, wherein N is a non-zero positive integer, an intelligent metamaterial unit structure comprises a metal structure layer, a surface-layer control diode, a dielectric plate layer, a total-reflection zero-transmission layer and a dielectric plate layer, all units can be used for achieving synchronous and independent real-time control by a programmable gate array, and four coding states can be generated and are corresponding tofour reflection phases of 0 degree, 90 degrees, 180 degrees and 270 degrees. The intelligent metamaterial is used for sensing position and angle of the metamaterial by a spectrometer, various types ofapplication such as beam deflection, special-mode orbital angular momentum beam and target radar cross section (RCS) reduction can be generated according to program setting in advance, so that the metamaterial is used for generating different electromagnetic responses under a special space state. The metamaterial has the advantages of simple-layer structure and the like and is easy to process.

Description

technical field [0001] The invention relates to a novel artificial electromagnetic material, in particular to an electromagnetic coding metamaterial with self-adaptive function in the microwave section. Background technique [0002] New artificial electromagnetic materials, also known as electromagnetic metamaterials (Metamaterials), are an artificial material composed of macroscopic basic units with specific geometric shapes arranged periodically / aperiodically, or implanted into the body (or surface) of the matrix material. . The difference between electromagnetic metamaterials and traditional materials is that the original microscopic units (atoms or molecules) are replaced by macroscopic units. Although the unit sizes of the two are quite different, their responses to external electromagnetic waves are reflected by the interaction between the basic unit resonant system and the external electromagnetic field. Electromagnetic metamaterials define the behavior of electroma...
