Dual-metasurface superlens: A comprehensive study
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 …
