Assigning a Independent Boundary for a 2D Electrostatic Solver

Independent and dependent boundaries enable you to model planes of periodicity where the E-field vector at every point on the dependent boundary surface is forced to match the E-field vector of every corresponding point on the independent boundary surface. The transformation used to map the E-field from the independent to the dependent is determined by specifying the orientation of a local, predefined coordinate system, indicated by an arrow, on both the independent and dependent boundaries.

To set an independent boundary:

1. Select the edge to which you want to assign the independent boundary.
2. Click Maxwell 2D > Boundaries > Assign > Matching > Independent.
   The Independent Boundary dialog box appears.
3. Enter a name for the boundary in the Name box, or accept the default.
4. To reverse the direction of the vector, select the Reverse Direction check box.
5. Click OK.
