摘要
本文研究一种时域有限差分法的三维曲面共形技术，将其用于抛物面及卡塞格伦天线的建模，所得近场分布与实验值等吻合较好。
A 3-D contour technique for curved surfaces in FDTD method is presented.It has been used in modeling the parabolid and Cassegrain antenna system.The near field distributions obtained are in good agreement with the values from other method and measured values.
