Claim:
1. A process for obtaining a material comprising a substrate coated on at least one portion of at least one of its faces with a coating comprising at least one discontinuous metallic thin layer based on silver, on gold, or on any alloy thereof, the or each discontinuous metallic thin layer being encapsulated between at least two dielectric thin layers, and the or each discontinuous metallic thin layer being in the form of periodic geometric patterns, said process comprising: depositing a coating on at least one portion of at least one face of said substrate, the coating comprising at least one continuous metallic thin layer based on silver, on gold, or on any alloy thereof, the or each continuous metallic thin layer being encapsulated between at least two dielectric thin layers, then making the substrate thus coated run opposite at least one laser device emitting a laser radiation focused on said coating in the form of at least one line, a power of said radiation being adapted in order to render the or each metallic thin layer discontinuous by dewetting.
