面向工程应用的电磁散射特性建模关键问题研究
|
摘要
随着计算电磁学和计算机技术的迅速发展,电磁散射特性建模技术从算法研究向产品化、集成化、工程化发展.文中分析了探测、识别、伪装等实际工程应用中对电磁散射特性建模技术的具体需求,总结了几何建模、网格剖分、电磁计算和模型验证等建模流程中存在的关键问题与解决方式,以及电磁散射建模技术的发展特点.
With the rapid development of computational electromagnetics and computer technology, electromagnetic scattering modeling and simulation technology has shifted from algorithm research to production, integration and engineering. This paper analyzes the engineering requirements for electromagnetic modeling and simulation technology, summarizes the key problems and solutions in electromagnetic modeling and simulation process such as geometric modeling, mesh generation, electromagnetic computation and model validation, and summarizes the characteristics of electromagnetic modeling and simulation technology.
