Single-junction quantum-circuit refrigerator
V. Vadimov, A. Viitanen, T. Mörstedt +2
We propose a quantum-circuit refrigerator (QCR) based on photon-assisted quasiparticle tunneling through a single normal-metal--insulator--superconductor (NIS) junction. In contras…
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…
Electromagnetic wave refraction at an interface of a double wire medium
Igor S. Nefedov, Ari J. Viitanen, Sergei A. Tretyakov
Plane-wave reflection and refraction at an interface with a double wire medium is considered. The problem of additional boundary conditions (ABC) in application to wire media is di…
