Focusing slabs made of negative index materials based on inhomogeneous dielectric rods

SERGENTU, V. V.; URSAKI, V. V.; TIGINYANU, I. M.; FOCA, E.; FÖLL, H.; BOYD, Robert W. (WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim, 2006)

We show the advantages of using inhomogeneous dielectric rods to design photonic crystals that behave as materials with negative refractive index. We found that the analysis of light scattering properties of inhomogeneous ...
Superlensing with plane plates consisting of dielectric cylinders in glass envelopes

FOCA, E.; SERGENTU, V. V.; DASCHNER, F.; TIGINYNAU, I. M.; URSAKI, V. V.; KNÖCHEL, R.; FÖLL, H. (WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim, 2009)

The approach of designing negative-refractive-index materials on the basis of dielectric rods with a gradient of the dielectric constant is tested experimentally. A triangular-lattice plane-parallel slab assembled from ...
