Gaussian Beam Wave
An incident Gaussian Beam wave propagates in one direction and is of Gaussian distribution in the directions perpendicular to its direction of propagation. The steps for assigning a Gaussian Beam Wave are the same as those for assigning Plane Wave. The only difference is that in this case Gaussian Beam Wave Options will appear as one of the tabs instead of Plane Wave Options on the Incident Wave Source dialog box. For more information see Plane Wave.
