摘要

利用矩量法和时域有限差分法的混合方法,可以有效地解决单一数值方法难以解决的电磁传播问题。本文对车载多天线系统在无线通信应用中的性能影响进行了严格的混合全波分析。为了快速解决这些复杂的电磁问题,对移动平台影响下高性能天线的高效设计和优化至关重要,开发了基于mpi的并行化策略。提供了安装在车辆上的线天线的联合MoM/FDTD模拟的应用,从而揭示了对天线性能的影响。

A hybrid MoM/FDTD approach for an efficient modeling of complex antennas on mobile platforms
The use of a hybrid Method of Moments (MoM)/Finite Difference Time Domain (FDTD) method can be effective for solutions of electromagnetic propagation problems, which are intractable for single numerical methods. This paper presents a rigorous, hybrid full-wave analysis of effects pertinent to vehicular multi-antenna system performance for wireless communication applications. For a fast solution of such complex electromagnetic problems essential for an efficient design and optimization of high performance antennas under the influence of mobile platforms, MPI-based parallelization strategies are developed. Applications where the combined MoM/FDTD simulation of wire antennas mounted on a vehicle sheds light into the impact on the antenna performance are provided.
