SquareUniformElectricField
==========================

.. java:package:: ch.epfl.leb.sass.models.illuminations.internal
   :noindex:

.. java:type:: public class SquareUniformElectricField implements ElectricField

   Creates a uniform electric field of square shape propagating in the +z-direction. This electric field is uniformly polarized and of the same magnitude within the area (0, width), (0, height). It extends from z = 0 to z = infinity. Obviously, it is not physical but is a good approximation of a plane wave with finite energy. The field propagates in the z-direction.
