The finite-difference time-domain method (FDTD) is one of the most powerful numerical methods for both acoustic and electromagnetic simulations. It is also one of the most efficient methods and extremely valuable for parallel computing. This method, however, has not been accurate enough to simulate sonar and radar systems due to the imperfect boundary conditions. Developing high performance absorbing boundary conditions for FDTD simulation is of major interest to many researchers in this field. Recently, a perfectly matched layer (PML) boundary condition was proposed by J. P. Berenger to solve the boundary problem with satisfactory accuracy. Berenger has shown through numerical simulations that his idea works very well for the 2-D TE mode EM wave case. Katz et al. extended this method to 3-D vector EM waves.

520 $a This dissertation focuses on extending and developing the PML boundary conditions for more general applications. Specifically, the PML boundary conditions have been extended to acoustic simulations. A dispersive PML (DPML) boundary condition is developed for matching ambient dispersive media. A state variable approach has also been developed to extend the FDTD method to simulate media with dispersion. The PML idea is also extended to simulate elastic wave propagation and scattering. Numerical simulations have been employed to prove the ideas and methods developed in this research.
