摘要

The pseudospectral time-domain (PSTD) technique is advantageous for modeling macroscopic light scattering problems but falls short to model a light source of realistic dimensions. We report a novel simulation technique that enables modeling a finite-width, continuous-wave (CW) light source within PSTD simulations that was infeasible before. By exploiting the mathematical characteristics of Maxwell's equations, the instability problem of the PSTD algorithm can be overcome. We demonstrate the reported simulation enables modeling the CW optical phase conjugation (OPC) phenomenon of light propagation through a scattering medium. Specific simulation findings show that monochromatic phase-conjugated light can be focused through scattering medium. On a wider scope, the reported method enables implementing a finite-width, CW, plane-wave light source in a PSTD simulation for general optics and electromagnetic problems.
