Abstract

The invention discloses a radiation and scattering integrated information metamaterial surface. The information metamaterial surface is composed of periodically or non-periodically arranged artificialelectromagnetic structural units, and has the ability of radiation electromagnetic field / wave regulation and scattering electromagnetic field / wave regulation, the unit constituting the information metamaterial surface has at least 1-bit unit code element, and the information metamaterial surface can be regulated within at least one electromagnetic physical domain. The information metamaterial surface solves the limitation that traditional metasurfaces are only used in the field of scattering or radiation, meanwhile has the ability to regulate and control electromagnetic waves in time-space-frequency-polarization and other multidimensional electromagnetic physical spaces in real time, that is, has more powerful comprehensive control capability, and has broad application prospects in high-performance antennas, smart antennas, new-system radars, new-system communication systems, and reduction of radar scattering cross sections, etc.

Description

technical field

[0001] The invention belongs to the technical field of novel artificial electromagnetic material surfaces, and in particular relates to a radiation and scattering integrated information metastructure material surface and its application. Background technique

[0002] Metamaterials refer to artificial composite structures formed by units with sub-wavelength scales in a certain macroscopic arrangement (periodic or non-periodic). Because its basic unit and arrangement can be designed arbitrarily, it can break through the limitations of traditional materials that are difficult to precisely control at the atomic or molecular level, and construct unconventional medium parameters that cannot be realized by traditional materials and traditional technologies, and then efficiently and flexibly control electromagnetic waves. , to achieve a series of novel physical properties and applications. In the past two decades, metamaterials have been the international frontier i...
