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:
- Go to the Setup tab > Environment panel >.
- Select the Substrate option in the Ground Plane box, Fig. 1.
- Choose an infinite or finite slab in the Substrate Slab Options box.
- 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.
