| abstract |
The invention concerns a method for obtaining a material comprising a substrate coated on at least a part of at least one of the faces of same with a coating comprising at least one discontinuous thin metal layer made from silver, gold, or any of the alloys of same, the or each discontinuous thin metal layer being encapsulated between at least two dielectric thin layers, and the or each discontinuous thin metal layer being in the form of periodic geometric patterns, said method comprising a step of depositing and then a step which involves conveying the substrate coated in this way in front of at least one laser device emitting laser radiation focused on said coating in the form of at least one line, the power of said radiation being suitable for making the or each thin metal layer discontinuous by dewetting. |
