Substrate and Superstrate
Révision datée du 14 décembre 2021 à 08:22 par Ouassila (discussion | contributions)
Substrate
Material on which the ALU structure is laid. It is assumed to be infinitely thick. For DALHAI, it is defined by its refractive index (n1 in pyGDM), which is a number. Generally the substrate is made of glass, so n1=1.5.
Superstrate
Semi-infinite medium in which the substrate + plasmonic structure are immersed. For DALHAI, it is simply defined by its refractive index (n2 in pyGDM), which is a number. Generally, the superstrate is air, so n2=1.
