摘要

We present a time domain hybrid method to realize the fast coupling analysis of transmission lines excited by space electromagnetic fields,in which parallel finite-difference time-domain (FDTD) method,interpolation scheme,and Agrawal model-based transmission line (TL) equations are organically integrated together.Specifically,the Agrawal model is employed to establish the TL equations to describe the coupling effects of space electromagnetic fields on transmission lines.Then,the excitation fields functioning as distribution sources in TL equations are calculated by the parallel FDTD method through using the message passing interface (MPI) library scheme and interpolation scheme.Finally,the TL equations are discretized by the central difference scheme of FDTD and assigned to multiple processors to obtain the transient responses on the terminal loads of these lines.The significant feature of the presented method is embodied in its parallel and synchronous calculations of the space electromagnetic fields and transient responses on the lines.Numerical simulations of ambient wave acting on multi-conductor transmission lines (MTLs),which are located on the PEC ground and in the shielded cavity respectively,are implemented to verify the accuracy and efficiency of the presented method.
