Ray tracing in plasma

  1. Jul 27, 2013 #1
    I'm studying wave propagation in the ionosphere, which can be modeled as a dielectric that has a magnetic field present. My understanding of it is that the Poynting vector that is associated with the wave in the medium is not generally in the same direction as the k vector (what I understand to be the vector normal to equiphase planes). If I were to do ray tracing between a transmitting antenna and receiving antenna (in the ionosphere, let's say), should I look at the ray traced by the Poynting vector or the k vector and which path is the group velocity associated with?
