Near-field enhancement and imaging in double cylindrical polariton-resonant structures: Enlarging perfect lens
Pekka Alitalo, Stanislav Maslovski, Sergei Tretyakov
We experimentally demonstrate a prototype of a cylindrical enlarging lens capable of enhancing and restoring evanescent fields. The enabling phenomenon is the resonant excitation o…
Sub-wavelength imaging: Resolution enhancement using metal wire gratings
G. Fedorov, S. I. Maslovski, A. V. Dorofeenko +3
An experimental evidence of subwavelength imaging with a "lens", which is a uniaxial negative permittivity wire medium slab, is reported. The slab is formed by gratings of long thi…
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…
Three-dimensional isotropic perfect lens based on LC-loaded transmission lines
P. Alitalo, S. Maslovski, S. Tretyakov
An isotropic three-dimentional perfect lens based on cubic meshes of interconnected transmission lines and bulk loads is proposed. The lens is formed by a slab of a loaded mesh pla…
Backward-wave regime and negative refraction in chiral composites
S. Tretyakov, A. Sihvola, L. Jylha
Possibilities to realize a negative refraction in chiral composites in in dual-phase mixtures of chiral and dipole particles is studied. It is shown that because of strong resonant…
Improving antenna near-field pattern by use of artificial impedance screens
Stanislav Maslovski, Pekka Ikonen, Constantin Simovski +3
An antenna prototype utilizing artificial impedance surfaces to control the near field distribution is described. The antenna is a folded dipole placed above a finite-size artifici…
