摘要：
The phenomenon of performance degradation due to transceiver misalignment is a common issue in Orbital Angular Momentum (OAM) communication systems. This paper introduces an anisotropic holographic metasurface, which demonstrates the alteration in the deflection angle of the target beam when the relative permittivity of the substrate is adjusted. The metasurface is constructed from subwavelength metallic patches placed on a grounded dielectric substrate. The surface impedance distribution of the proposed holographic metasurface is determined by the interference between the excitation source and the predefined object beam.
