本文研究了NURBS‐UTD方法在分析理想导电凸曲面上天线组辐射问题中的应用。为了利用参数曲面的映射定义，在参数域上建立了电磁射线路径的数值算法。该算法适用于任意形状的曲面，为以后的电磁场计算提供了准确、稳定的几何参数。用圆柱体对该算法进行了验证，得到了射线路径的解析解，通过比较，两者吻合较好。计算了安装在任意形状表面上的天线的辐射方向图，并与商业软件进行了比较，以验证所提出的方法的准确性和能力。以均方根误差评价，该方法与商业软件的误差在1dB左右。
This paper studies the use of NURBS‐UTD method in analyzing radiation of antenna set on perfectly conducting convex surfaces. The electromagnetic ray path is traced by numerical algorithm built from parametric domain in order to take advantage of the mapping definition for parametric surfaces. The presented algorithm can be applied to arbitrary shaped surfaces and provide accurate and stable geometrical parameters to calculation of electromagnetic fields afterwards. The algorithm is verified by cylinder on which analytical solution of ray path is available and good agreement is achieved by comparison. Radiation patterns of antennas mounted on arbitrary shaped surfaces are calculated and compared to commercial software to testify the accuracy and ability of the presented method. Evaluated by RMS error, the deviation between the presented method and commercial software is about 1 dB.
