Plane of incidence

  1. Jun 30, 2014 #1
    How to define the plane of incidence for normal incidence of a plane polarized wave?
    Is the reflection coefficient defined by ordinary, extraordinary, or the combination of both waves?

    Thanks for the help!

    The usual method is to define one line with the wave vector (normal to the plane wave), which is then fixed by a point of incidence at the material surface. The vector normal to the surface at that point gives you a second vector .... these then define the plane of incidence. The k-vector for the reflected wave will be in this plane.

    If the wave vector is normal to the surface there is no unique plane of incidence.
