The analytical vectorial structure of HGB is investigated in the far field based on the vector plane wave spectrum and the method of stationary phase. The energy flux distributions of HGB in the far-field, which is composed of TE term and TM term, are demonstrated. The physics pictures of HGB is illustrated from the vectorial structure, which is important to understand the theoretical aspects of both scalar and vector HGB propagation.
基于矢量平面波谱和驻相法，在远场研究了高增益布洛赫波（HGB）的解析矢量结构。展示了由TE项和TM项组成的HGB在远场的能流分布。从矢量结构阐述了HGB的物理图像，这对于理解标量和矢量HGB传播的理论方面很重要。
