Kuvaus

We present a theoretical and numerical study of a dual-metasurface superlens dedicated to the near-field optical imaging of submicron objects. Compared to the previous studies of dual-metasurface plasmonic superlenses, we suggest a more adequate theoretical model of their operation. The new model allows us to obtain twice better operational characteristics of the redesigned superlens. For the first time, we describe the operation of such the superlens using full-wave numerical simulations, taking into account the interfaces of the host medium slab and proving the nanoimaging for scattering objects instead of radiating sources. We discuss and address both application and fabrication issues for this superlens.
