Hey,
I'm trying to simulate a light soliton using FDTD with Mur's boandary conditions.
The results don't explode but I get funny solutions (Sometimes the soliton loses amplitude, sometimes it gains amplitude...) that change when I choose different resolutions for the simulation that should all be small enough for this sort of simulations (lambda/10, lambda/15, lambda/25, lambda/50).
I've checked my code time and time again but the explanation for the problem eludes me.
Does someone have a working 2D (or 3D) nonlinear Kerr effect FDTD simulation that I could look at?
I've attached my matlab FDTD function. It explains itself using elaborate notes. It uses normalized coefficients (c=1...). You can't run simulations using the code alone (you need to create a few files using other matlab codes.
I would appreciate it if you could give it a look and tell me if you see something wrong with it.
Thanks.
