Add a thin dielectric sheet to a face bordering a free space region.
        The thin dielectric sheet approximation changes the
            surface impedance of triangular elements. Only the boundary condition is
            affected.

                Create the layered dielectric to use as a thin dielectric sheet:
                
                    - 
                        Define the dielectric(s).
                    
 
                    - 
                        Define the layered dielectric.

                In the details tree select the face where you want to apply
                    the thin dielectric sheet.

                On the Modify Face dialog, click the
                        Properties tab.

                Under Face medium, in the Medium
                    drop-down list, select the layered dielectric medium to be
                    used as the thin dielectric sheet.

                Click OK to apply the thin dielectric sheet to the
                    face and to close the dialog.
