On geometrical scaling of split-ring and double-bar resonators at optical frequencies
Sergei Tretyakov
In this paper we consider the resonant frequency of split-ring resonators and double-bar resonators used to create artificial magnetic response at terahertz and optical frequencies…
On Impedance Bandwidth of Resonant Patch Antennas Implemented Using Structures with Engineered Dispersion
Pekka Ikonen, Pekka Alitalo, Sergei Tretyakov
We consider resonant patch antennas, implemented using loaded transmission-line networks and other exotic structures having engineered dispersion. An analytical expression is deriv…
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…
Microstrip antenna miniaturization using partial dielectric material filling
Olli Luukkonen, Pekka Ikonen, Sergei Tretyakov
In this paper we study microstrip antenna miniaturization using partial filling of the antenna volume with dielectric materials. An analytical expression is derived for the quality…
Bianisotropic route to the realization and matching of backward-wave metamaterial slabs
Sergei A. Tretyakov, Constantin R. Simovski, Martin Hudlicka
A concept of backward-wave bianisotropic composite medium matched to free space is suggested. It is based on the use of a uniaxial bianisotropic structure embedded into a matrix wi…
