Even Symmetry

An even symmetry boundary models a structure in which the signs (positive or negative) of the currents, voltages, or charges on one side of a symmetry plane are the same as those on the other side. The magnetic field is perpendicular to this type of boundary; while the electric field is tangential to this type of boundary, and contours of equal potential are perpendicular to it.

To define an even symmetry boundary, the simulator sets the selected edge to a Neumann boundary.

For instance, the plane of symmetry shown below could be modeled by an even symmetry boundary, since the direction of the current flow in the conductor on the left side of the symmetry plane is the same as that of the current flow in the conductor on the right side of the plane (the side that is modeled):
