Model a slot or aperture in an infinite plane using the planar Green's function
aperture. The aperture is discretised instead of the surrounding ground plane, reducing the
number of triangles and run time.
Create the geometry to model the aperture or slot in the infinite PEC plane.
For example, create a rectangle to represent the aperture.
Select the “aperture” in the 3D view or in the
model tree.
In the details tree, from the right-click context menu, select Properties.
On the Modify Face dialog, click the
Solution tab.
Under Solve with special solution method, from the
drop-down list, select Planar Green's function
aperture.
Click OK to model the aperture as a planar Green's
function aperture and to close the dialog.
