Dispersion
{

 - Propagation of a laser beam in a plasma.  This input file is meant
   as a benchmark of OOPIC vs. theory.

 - A plane EM wave is introduced in x-y geometry from the left, which
   hits a plasma interface.  The idea is to measure the wavelength
   in the plasma for various frequencies to measure the dispersion.

 - In this case, the incident wave is at 1.4wp
