The fast decay of the solutions in certain directions of the complex plane is used to improve parabolic wave equation solvers: the solution is marched on a suitably chosen contour in the complex plane rather than on the real line. This interpretation of Bérenger's perfectly matched layer allows extremely efficient truncation of the computational domain with a split–step/Fourier algorithm. The theory is developed for both the wide–angle and narrow–angle parabolic wave equations, and numerical results are presented.
