论文摘要
轨道角动量(OAM)由于其相分布而逐渐成为雷达,通信和其他领域的研究热点。但是,由于其固有的特征,它在实际实践中遇到了一些问题。最近,已经提出了OAM模式组来解决这些问题。在本文中,使用非均匀的OAM源来直接生成OAM模式组(MG)。基于等效源变换分析辐射场。以部分ARC传输(PAT)方案为例,通过计算其傅立叶变换,将非均匀的源等于一组均匀的OAM源。这项工作为RF域中的不均匀OAM天线设计提供了理论指导。
Orbital angular momentum (OAM) has gradually become a research hotspot in radar, communication and other fields because of its phase distribution. However it encounters some problems in the real practice owing to its inherent characteristics. Recently OAM mode group has been proposed to solve these problems. In this paper, a non-uniform OAM source is used to generate the OAM mode-group (MG) directly. The radiation field is analyzed based on an equivalent source transformation. Taking the partial arc transmitting (PAT) scheme as an example, the non-uniform source is equivalenced as a group of uniform OAM sources by calculated its Fourier transform. This work provides theoretical guidance for the design of non-uniform OAM antenna in the RF domain.
