Abstract :
Two finite-difference time-domain (FDTD) algorithms for computing scattered electromagnetic fields are compared. The Yee algorithm is compared to a characteristic-based algorithm using a simple two-dimensional geometry. The scattered fields of a conducting strip give an incident transverse magnetic (TM) short-duration Gaussian pulse are computed using both algorithms. The characteristics of the scattered fields are compared
