A 2D finite-difference time-domain (FDTD) framework for studying nonlinear electromagnetic wave-wave coupling across four physics regimes: linear vacuum, Kerr media, cold ...

How do you cleanly measure two electromagnetic waves interacting with each other, separated from each wave's self-interaction with the medium? This framework introduces a linearity residual diagnostic ...
