Spatial filtering with rough metal-dielectric layered metamaterials

Marcin Stolarek, Piotr Wróbel, Tomasz Stefaniuk, Mateusz Wlazło, Anna Pastuszczak, Rafał  Kotyński


Imaging through layered metal-dielectric optical metamaterials may be modeled as linear spatial filtering. We characterize the filtering properties of a thin metal-dielectric-metal multilayer structure evaporated by physical vapor deposition. We present the measurements of transmission spectra, and of surface roughness, as well as the simulation results showing the sensitivity of the structure properties to surface roughness. Surface roughness is found to be the major factor that limits the theoretical filtering properties of the structure.
