An electrically heated window is disclosed which achieves a more uniform current density at the interface between the resistive heating layer and the current-bearing electrodes to which it is connected. In one embodiment this may be achieved by forming the edge of the electrode in an undulating shape. It may also be done by increasing the surface resistance of the electrode near its edge by, for example, forming the edge so that it is wedge-shaped in cross-section. More uniform current density may also be achieved by using an electrode which has a resistivity that is greater than that of the resitive heating layer. It may also be achieved by use of a high resistivity layer located between the electrode and the resistive heating layer. |
