Help comsol particle tracing

  1. May 2, 2014 #1
    I would like to simulate a beam of light that is incident on a sphere with a refractive index and you get the total internal reflection, I would like to use ray tracing in COMSOL 4.3a. you have any advice on this?

    Should I apply the law of snell and I can not figure out what expression to use: Newtonian, Lagrangian, Hemiltonian or massless. I hope someone can help me
