摘要
复杂电磁环境的研究包括多方面内容,其中飞行器的电磁环境效应研究受到了较多的关注。随着计算机技术的飞速发展,利用数值模拟技术获得飞行器电磁特性已经成为飞行器电磁环境效应研究的一个重要手段。我们将自主研发的大规模并行三维时域全波电磁模拟软件JEMS-FDTD应用于运输机整机电磁特性仿真,计算并分析了飞机的电磁耦合散射特性,获得了飞行器在电磁脉冲照射下的时域/频域、近场/远场等电磁信息。计算中为保证精度采用了非均匀以及高阶FDTD计算技术。
Abstract
Research on the electromagnetic environment effect of aircraft has received attention in study of complex electromagnetic environment. With the rapid development of computer technology, using numerical simulation technology to obtain the electromagnetic characteristics of vehicle has become an important means to study aircraft electromagnetic environment effects. This paper demonstrated a massively parallel 3D full-wave electromagnetic field simulation program software JEMS-FDTD and its application to electromagnetic characteristics simulation of a transport plane, and obtained the electromagnetic information in pulse irradiation, such as the time and frequency domain, and near field/far field and electromagnetic distribution. In order to ensure the accuracy of the calculation, a non-uniform and high order FDTD computing technology was used.
