| 摘 要： | 本文根据微分几何原理,从广义费马原理出发,导出了适用于圆锥和圆柱体上天线绕射线的寻迹方程。求解寻迹方程,便得到曲面绕射线的轨迹和边缘绕射点的位置,从而可以计算它的绕射场。最后,给出一些理论和实验数据,得到了令人满意的结果。

| Abstract: | A tracing equation of diffraction rays is developed by applying the extensive Famat'sprinciple and differential geometry.This equation is applicable to the antenna on cone andcylinder.By solving these equations,the diffraction trace of a curved surface and the posi-tion of the edge's diffraction point are determined so that the diffraction field can be ob-tained.Some theoretical and experimental datas are given and satisfactory results are ob-tained. |
