论文摘要
本文介绍了孔径场估计（AFE）技术和绝热浮球波（AFW）扩展方法的结合，用于分析能够产生轨道角动量（OAM）涡流波的漏水全息图。在这些制剂中，从理论上估计了传播和泄漏常数，因此计算了孔径和远区域。这种理论方法可以显着降低计算复杂性，使得对具有较大尺寸的全息图的分析在记忆需求较低的情况下可以进行大尺寸的分析。各向同性和各向异性单位细胞用于实现全息图，各向异性结构在控制波极化方面表现出更好的性能。全息图旨在生成M = 2拓扑电荷的涡流梁，并且在微波处理中产生圆形极化状态。为了评估所提出方法的准确性，比较了理论模型和全波模拟的结果，并具有良好的一致性。
This paper presents the combination of aperture field estimation (AFE) technique and adiabatic Floquet-wave (AFW) expansion method for the analysis of leaky-wave holograms capable of generating orbital angular momentum (OAM) vortex waves. In these formulations the propagation and leakage constants are theoretically estimated and as a result the aperture field and far-zone field are calculated. This theoretical approach significantly reduces the computational complexity in such a way that the analysis of holograms with large dimensions is possible with low memory requirements. Isotropic and anisotropic unit cells are used to realize the holograms, which anisotropic structures show better performance in the control of wave polarization. The holograms are designed to generate vortex beams with topological charge of m=2 and circular polarization states in the microwave regime. To evaluate the accuracy of the proposed method, the results of theoretical model and full-wave simulations are compared, with good agreement.
