Abstract :
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 optimisation 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.
