Abstract :
A new time domain wave propagator (TDWP) based on the two-dimensional finite-difference time-domain (FDTD) technique (for original paper see ibid., vol. V-14, p. 302-307 (1966)) that was introduced in May 2000 issue) has been augmented in this paper so that it deals with impedance boundary condition or varying terrain heights and an example of each, with comparisons to other methods is presented.
