Abstract :
A complete electrical wire link between equipment boxes is analyzed using a theoretical method based on the finite-difference time-domain (FDTD) algorithm. This paper describes how the asymmetry of the transmission line created by different terminations has a direct impact on the radiation level. Thereafter, a transient experimental method is proposed to evaluate the behavior of localized defects on transmission links. The transient results lead to (S) parameters and radiation power. Simulations using the FDTD method validate the experimentation
