Successful applications of PML-ABC to the symplectic FDTD scheme with 4th-order accuracy in time and space

摘要

Successful applications of the perfectly matched layer (PML)-absorbing boundary condition (ABC) to the symplectic finite-difference time-domain (FDTD) scheme are demonstrated. The scheme employs the 4th-order symplectic integrator propagator. The scheme is highly accurate and memory savable. This demonstration opens the door to the practical application of the scheme.
