Abstract
A system of layers applied to a transparent substrate includes a first layer of an oxide such as ZnO or SnO.sub.2, a second layer of a substoichiometric oxide of Zn or Ta, a third layer of Ag or Cu, a fourth layer of a substoichiometric oxide of Ti, Cr, or Nb, and a fifth layer of similar composition as the first layer. The layers are preferably deposited by magnetron cathode sputtering in an atmosphere which consists of inert gas and, in the case of the oxide layers, a reactive gas.
