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.
