| 摘 要： | 用几何光学—单一平面波射线跟踪技术解决电大尺寸多层介质罩内电磁波传播问题的关键任务是求解射线与各介质分界面的交点,尤其是该文的背景课题为了考虑介质分界面曲率的影响,需要计算波阵面的曲率矩阵,因此有必要用更严格的方法来求射线与曲面的交点。该文论述了在已知天线罩各介质分界面曲面方程的情况下,如何用数值方法中的二分法来计算射线和介质分界面的交点,其算法直观、可靠,而且适用的曲面方程形式广泛。

| Abstract: | When applying GO associated with monochromatic plane wave ray tracing technique to analyze how electromagnetic wave propagates through large wavelength multi-layered radome,the exact point where one ray penetrates through a boundary surface must be determined,especially when curvature of wave front is wanted.Based on method of bisection,this paper presents an algorithm used to solve the intersecting point assuming that the equation of each boundary surface is definite.The algorithm advantages in its simplicity,accuracy and being adaptive for various kinds of surface. |
