Homework Help: Waves: Poynting vector

  1. May 11, 2008 #1
    I have the following homework problem: a monochromatic plane wave travels from medium 1 to medium 2 and experiences total internal reflection. Find the normal and parallel components of the Poynting vector, discuss the results with respect to the wave's polarization.

    Now, I think that the vector just doesn't depend on the polarization, and the calculation is pretty simple, so either the problem is trivial or I don't understand something. Any hints?

    A circularly polarized wave changes sense upon reflection.

    Regards,
