Paper Abstract

We examine several of our recent findings regarding field evolution methods. We focus particularly on three-dimensional solution algorithms for wide-angle wave equations including Lanczos, hybrid finite-difference/fast Fourier transform and finite-difference/Lanczos procedures. A novel alternating directional implicit formalism for general paraxial vector wave equations is considered and its stability and applicability to problems of practical interest are discussed in some detail. We also examine methods for stabilizing wide-angle vector algorithms and examine the role of modified Pade approximants and of appropriate dissipative boundary conditions. Finally, we compare the effectiveness of absorbing and transparent boundary conditions and consider the relative advantage which may be realized by employing both conditions simultaneously.
