Nanostructures for very broadband or multi-frequency transition from wave beams to a subwavelength light distributions
O. Luukkonen, J. Pniewski, C. Simovski
In this paper we suggest and theoretically study a tapered plasmonic nanostructure which connects the incident wave beam with a subwavelength spatial region where the field is loca…
Metamaterial nanotips
C. Rockstuhl, C. R. Simovski, S. A. Tretyakov +1
Nanostructured metamaterials, especially arrays of metallic nanoparticles which sustain the excitation of localized plasmon polaritons, provide excellent opportunities to mold the…
Towards isotropic negative magnetics in the visible range
C. R. Simovski, S. A. Tretyakov
The idea of isotropic resonant magnetism in the visible range of frequencies known from precedent publications is developed having in mind achievements of the modern chemistry. Pla…
Comment on "Guiding, Focusing, and Sensing on the Subwavelength Scale Using Metallic Wire Arrays"
Pavel A. Belov, Mario G. Silveirinha, Constantin R. Simovski +2
This is a comment on "Guiding, Focusing, and Sensing on the Subwavelength Scale Using Metallic Wire Arrays" by G. Shvets, S. Trendafilov, J. B. Pendry and A. Sarychev published in…
Near-field enhancement and sub-wavelength imaging in the optical region using a pair of two-dimensional arrays of metal nanospheres
Pekka Alitalo, Constantin Simovski, Ari Viitanen +1
Near-field enhancement and sub-wavelength imaging properties of a system comprising a coupled pair of two-dimensional arrays of resonant nanospheres are studied. The concept of usi…
Frequency range and explicit expressions for negative permittivity and permeability for an isotropic medium formed by a lattice of perfectly conducting particles
Constantin R. Simovski, Sailing He
An analytical model is presented for a rectangular lattice of isotropic scatterers with electric and magnetic resonances. Each isotropic scatterer is formed by putting appropriatel…
