摘要 开放的图形程序接口(OpenGL)是一个国际组织提供的规范,可以跨平台使用,是一个功能强大,调用方便的底层3D图形库;时域有限差分(FDTD)算法是解决电磁场问题的简单而又有效的数值方法。把两者结合并利用计算机可视化技术,对目标系统进行电磁建模研究,实现了电磁建模模块的三维可视化设计。该建模模块可用于进行目标物体的三维可视化建模和电磁学参数描述及仿真数据预处理。微带耦合器的建模实例表明该电磁建模模块数据处理具有高效性、可靠性和良好的三维可视化效果。 A cross -platform standard offered by international organization, OpenGL (Open Graphics Library) is a powerful and convenient bottom 3D graphics library. Finite Difference Time Domain (FDTD) algorithm is a simple and efficient numerical method used for solving electromagnetic problems. Design of 3D visualization of electromagnetism modeling module can be realized by combining the two and using computer visualization technology and researching into electromagnetism modeling module of the objects. The module is used for 3D visualization modeling of the target objects, describing electromagnetic parameters and preprocessing simulation data. Microstrip coupling Modeling examples prove that the data processing of electromagnetism modeling module is efficient, dependable and of good 3D visualization performance.
