A new time domain wave propagator (TDWP) based on two-dimensional finite-difference time-domain (FDTD) technique (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.
