摘　　要：介绍三维全波电磁分析软件的算法实现和主要功能,软件包含电磁建模和FDTD数值求解两大模块,可用于射频微波等系统的电磁场分析和设计。自动进行满足FDTD算法条件的均匀和非均匀网格划分,生成描述介质、网格、边界条件、激励源设置等所需的数据文件。通过对目标物体进行平移、旋转、缩放等操作可以进行实时观察与修改,具有较强的电磁建模效率和三维可视化效果,实现了计算区间内电磁场的动态变化演示。通过在实际工程中的应用,以及和商用软件HFSS的对比,验证了软件的功能和应用价值。The algorithm realisation and main functions of 3D full-wave electromagnetic analysis software are addressed.The software consists of two main modules：the electromagnetic modelling and the FDTD numerical solver,it can be used in electromagnetic field analysis and design for systems of radio frequency and microwave,etc.The software conducts uniform and non-uniform mesh generation automatically in accord with FDTD algorithm conditions,forms data files needed by describing media,mesh,boundary condition,stimulus source setting,etc.It is convenient to observe and modify the targeted objective timely by translating,rotating and scaling operations,has quite high electromagnetic modelling efficiency and 3D visualised effect,which implements the dynamic variation demonstration of electromagnetic field in computation interval.The functions and applied value of the software have been verified through practical project application as well as the comparison with commercial software HFSS.
