      Plasmonic super-oscillations and sub-diffraction focusing 

      Yuan, Guanghui; Rogers, Edward T F; Roy, Tapashree; Du, Luping; Shen, Zexiang; Zheludev, Nikolay I (2014)
      We demonstrate experimental focusing of surface plasmon polaritons beyond the plasmon diffraction limit using a super-oscillatory plasmonic antenna at the wavelength of 785nm, achieving a hot-spot as small as 300nm.

      UV & visible plasmonic metamaterials made of topological insulator 

      Ou, Jun-Yu; So, Jin-Kyu; Adamo, Giorgio; Sulaev, Azat; Wang, Lan; Zheludev, Nikolay I. (2014)
      Plasmonic resonances are observed in metamaterials made of a topological insulator, Bi1.5Sb0.5Te1.8Se1.2, at the UV and visible frequencies due to the material’s interband transition and nontrivial surface conducting state.
