Problems solved by technology

At present, most of the metasurfaces applied in the terahertz frequency band are designed with metal units. Because the skin effect of metal itself in the higher frequency THz frequency band is serious, the current is concentrated on the metal surface, and the uneven current distribution causes the unit Impedance increases, resulting in higher loss across the metasurface, which is not conducive to practical applications

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 three-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 re...
