An Efficient Modeling Technique for Time Domain Field-to-Wire Coupling in the Massively Parallel Computer Codes JEMS-FDTD

A time domain field-to-wire coupling technique has been developed and integrated into the massively parallel computer codes JEMS-FDTD, allowing us to model wires and cables inside an electrically large and complex objects with high efficiency. The induced effects of wires and cables are retrieved by solving the transmission line equations using the one-dimensional (1D) finite difference time domain (FDTD) method. The JEMS-FDTD codes with the field-to-wire coupling technique have been validated by calculating the field coupling effects of a single-core wire positioned along the axis and off axis above a PEC ground plane. The JEMS-FDTD codes have also been applied to analyze the induced effects of an obliquely positioned single-core wire inside a vehicle upon a plane wave excitation.
