摘要

提出了一种用于机载天线电磁场分析的FDTD-ABT混合方案。混合方法采用球面波展开将时域有限差分代码与ABT代码连接起来，即使用球面谐波为ABT提供用时域有限差分建模的源的合适描述。这种方法利用时域有限差分处理天线及其附近结构的详细模型的能力，而ABT能够执行卫星环境的分析。

Astigmatic beam tracing hybridised with FDTD for on board antenna analysis

An hybrid FDTD-ABT scheme has been proposed for the electromagnetic field analysis of an on board antenna. The hybrid method resorts to a spherical wave expansion to link the FDTD code to the ABT code, i.e. spherical harmonics are used to provide ABT with a suitable description of the source modelled with FDTD. This approach exploits the ability of FDTD to treat detailed models of the antenna and its nearby structures while ABT is able to perform the analysis of the satellite environment.
