There is pieces of wire running back and forth across the window in rows., I dont recall what they are made off. But anyways these wires are heated when you turn on the back defroster, thus resulting in the melting of snow, ice, whatever and leaving the lines on the window until the ice is gone.

some windows also have a very thin film of gold between two layers of glass that heats and clears the window,similar to aircraft windshields
