Abstract

Gold-core/palladium-shell metamaterials for hydrogen detection are presented. The more than 30%2change in both the reflection and transmission from the metamaterial layer that is observed when the layer is exposed to 2%2hydrogen mixture is clearly noticeable to the naked eye as a change in the brightness of light transmitted by the metamaterial. This sensor should make a contribution to the safety of processes involving hydrogen.
