Fig. 1From: Nanoporous Anodic Alumina 3D FDTD Modelling for a Broad Range of Inter-pore DistancesSchematic cross sections of the different geometrical models. a First model with flat interfaces between the aluminium substrate and the porous layer. b Second model with the texturization of the interfaces with hemispherical concavities. c Third and fourth models with the dual layer structure in the pore walls, without and with absorption, respectivelyBack to article page
