Abstract

The invention discloses a graphene metasurface construction method used for spin angular momentum deflection in a two-dimensional direction. The method is applied to a computer device and comprises the following steps of: constructing a graphene reflection unit which comprises a graphene patch at the uppermost layer, a quartz dielectric plate at the middle layer and a metal floor at the bottom layer; inputting the number of graphene reflection units required by the graphene metasurface to be constructed; calculating the phase distribution of each position of the graphene metasurface to be constructed to determine the arrangement positions of all graphene units forming the graphene metasurface; and combining all the graphene units into the graphene metasurface according to the arrangement positions of all the graphene units of the graphene metasurface to be constructed. According to the embodiment of the invention, the graphene reflection unit is used for constructing the graphene metasurface, and the spin angular momentum and the deflection direction of electromagnetic waves in the two-dimensional direction can be controlled.

Description

technical field [0001] The invention relates to the technical field of microwave communication, in particular to a method for constructing a graphene metasurface with spin angular momentum deflection in a two-dimensional direction. Background technique [0002] In recent years, the technology of controlling the spin angular momentum (SAM) and orbital angular momentum (OAM) of electromagnetic waves has gradually attracted people's research interest, because they can be applied to the polarization diversity and channel coding of communication systems, etc. There are researchers designing metasurface devices to tune them independently. These two kinds of momentum are intrinsic properties of a propagating electromagnetic wave, and they are related to the polarization and phase of the electromagnetic wave, respectively. Due to the flexibility of metasurfaces in controlling the polarization and phase of electromagnetic waves, they are widely cited for irregular reflection or refr...
