Artificial magnetism and left handed media from dielectric rings and rods
L. Jelinek, R. Marques
It is shown that artificial magnetism with relatively large frequency bandwidth can be obtained from periodic arrangements of dielectric rings. Combined with dielectric rods, diele…
Balanced right/left-handed mixtures of quasi-planar chiral inclusions
R. Marques, F. Mesa, L. Jelinek +1
Some novel quasi-planar chiral inclusions, feasible from standard photo-etching techniques, are proposed. It is shown that such inclusions can be designed in order to present balan…
Unified Homogenization Theory for Magnetoinductive and Electromagnetic Waves in Split Ring Metamaterials
J. D. Baena, L. Jelinek, R. Marques +1
A unified homogenization procedure for split ring metamaterials taking into account time and spatial dispersion is introduced. The procedure is based on two coupled systems of equa…
Near-field imaging in the megahertz range by strongly coupled magnetoinductive surfaces: theoretical model and experimental validation
Manuel J. Freire, Ricardo Marques
In this work, near-field imaging by two strongly coupled arrays of split ring resonators is analyzed. A simple theoretical model is developed to obtain the transfer function of the…
Three dimensional super-resolution in metamaterial slab lenses
F. Mesa, R. Marques, M. Freire +1
This letter presents a theoretical and experimental study on the viability of obtaining three dimensional super-resolution (i.e. resolution overcoming the diffraction limit for all…
A planar magneto-inductive lens for three-dimensional subwavelength imaging
Manuel J. Freire, Ricardo Marques
A planar near-field magnetoinductive lens operating in the microwave range is presented. The proposed device consists of two parallel planar arrays of metallic broadside coupled (B…
