Abstract
The finite-difference time-domain (FDTD) method provides a numerical technique for solving acoustic forward problems. The FDTD is particularly useful in geometries that encompass heterogeneities. Plane-wave modeling permits the simulation of many practical bioacoustic problems because the phase front in the focal zone of many acoustic transducers is nearly planar. The formulation presented in this paper provides a technique for solving half-space problems under local plane-wave illumination.
