Abstract :
We have demonstrated the superb performance of the complementary operators method (COM) and its concurrent variant in suppressing reflection from computation boundaries with the finite-difference beam propagation method. We have applied them in modeling linear and nonlinear wave propagation in multidimension. Numerical examples show that C-COM performs better and requires less storage with slightly faster speed in most cases.
