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…
The influence of complex material coverings on the bandwidth of antennas
S. A. Tretyakov, S. I. Maslovski, A. A. Sochava +1
The influence of material coverings on the antenna bandwidth is investigated for antennas formed by thin electric or magnetic line sources. It is shown that uniform thin layers of…
A Numerical Study of Evanescent Fields in Backward-Wave Slabs
M. K. Karkkainen, S. A. Tretyakov, S. I. Maslovski +1
Numerical study of evanescent fields in an isotropic backward-wave (BW) (double negative or "left-handed") slab is performed with the FDTD method. This system is expected to be abl…
The planar perfect lens: physical requirements and possible alternative realizations
Stanislav Maslovski, Sergei Tretyakov
Several alternative possibilities of how to create an electromagnetic device being able to reconstruct near-field distribution of a source with sub-wavelength resolution (so-called…
Evanescent modes stored in cavity resonators with backward-wave slabs
S. A. Tretyakov, S. I. Maslovski, I. S. Nefedov +1
As was shown by N. Engheta, electromagnetic fields in two adjacent slabs bounded by two metal walls can satisfy the boundary conditions even if the distance between the two walls i…
Waves and energy in chiral nihility
Sergei Tretyakov, Igor Nefedov, Ari Sihvola +2
A model for a chiral material in which both the permittivity and permeability are equal to zero is discussed. Such a material is referred by us as a ``chiral nihility". It is shown…
