How to simulate EM waves/light in Python/Numpy

I decided to upload all the other wave propagating vids that I have sitting on my hard-drive and also give you a bit of info on how you can do your own simulations in Python.
This is a short demonstration showing simulation of a wave propagating from a point source plus a demo of a plane wave propagating through a slab of a high refractive index material.

I in a few days I will put a link here directing you to the Python codes that I used.

You can find the codes here:

[h.e.a]

what source function you used to simulate the equations??

Hi James, do you have a version of this code with periodic or absorbing boundary conditions? I have been trying to add them myself but not managed it yet

Hi James do you have any model of stabilizing waves, actual simulation if yes, please make video about it. However, if you don' t can you direct me how I can do by materiel so, i can do it my self .

It would be better to run in that video. I got error msg

Hey!! Any chance you might post the code somewhere??
Thanks for sharing this -- it's good stuff!!
