Responses of Twisted-Wire Pairs with and without Dielectric Coatings in the Presence of High-Power Electromagnetic Pulses (HP-EMP)

Induced responses of twisted-wire pairs with and without dielectric coatings are studied in this paper for different incident directions of the high-power electromagnetic pulses (HP-EMP), which can be fast-, medium-, and slow-EMP described by double-exponential function or even ultra-wideband triple-exponential function. 1-D finite-difference time-domain (FDTD) method is implemented for our simulation. This study should be useful for the development of certain protection technique for suppressing these intentional electromagnetic interference (IEMI) effects effectively.
