Incident Plane Wave
In the example shown a Regular/Propagating plane wave set up was used. There are also other plane wave options that you can use as applicable.
On the Incident Wave Source dialog box click the Plane Wave Options tab to define the type of plane wave.
On this panel you can set the plane wave as a Regular/Propagating which is the default or Evanescent. The last option will make the E field to be elliptically polarized.
A plane wave is described by the following equation.
For evanescent wave k = (b + ja).
Evanescent waves do not depend upon the background global material.
Note: See Polarization of the Electric Field for a technical discussion of polarization angles, and a definition of Polarization Ratio.
