Adding a Dielectric Substrate

A dielectric substrate, located below the xy-plane (Z < 0), can be added to the model by means of the following procedure:

  1. Go to the Setup tab > Environment panel >.
  2. Select the Substrate option in the Ground Plane box, Fig. 1.
  3. Choose an infinite or finite slab in the Substrate Slab Options box.
  4. Specify the substrate Permittivity and Thickness (h). Also set the widths along the X and Y axes if a finite slab has been chosen.

The substrate slab is backed up by a PEC ground plane parallel to the xy-plane and located at Z = -h. This ground plane cannot be removed from the simulation.
