Abstract: A transparent substrate comprises glass and is provided with a thin-film stack including a plurality of functional layers. The thin-film stack comprises at least three silver-based functional layers. The thin-film stack has a resistance R?<1.5 ? per square. The transparent substrate may undergo at least one transformation operation involving a heat treatment at a temperature of at least 500° C., so as to make it possible to achieve, using the substrate, alternatively or cumulatively, thermal control and/or electromagnetic shielding and/or heating.

Abstract: A method of supplying an electrically controllable system having variable optical/energy properties in transmission or in reflection, including at least one carrier substrate with a multilayer that allows migration of active species, including at least two active layers separated by an electrolyte, the multilayer being placed between two electrodes connected respectively to upper and lower current leads respectively. In addition to a constant first energy potential, a time-varying second energy potential is applied between the current leads, the first and second energy potentials being designed to ensure switching between two states having different optical/energy properties in transmission or reflection.
