Development of left-handed composite materials and negative refracting photonic crystals with subwavelength focusing
(2005)We review the studies conducted in our group concerning electromagnetic properties of metamaterials and photonic crystals with negative effective index of refraction. In particular, we demonstate the true left handed ... -
Electromagnetically induced left-handedness in a dense gas of three-level atoms
(The American Physical Society, 2004)Ways in which a three-level system can be used to change the frequency-dependent magnetic permeability of an atomic gas were discussed. The resulting macroscopic electrodynamics was also discussed. The two levels were ... -
EU NoE metamorphose: Metamaterials research activities
(2005)We will present the activities of METAMORPHOSE a network of excellence (NoE) formed under EU-FP6 on the area of metamaterials. The main scientific objective of the partners of this consortium is to develop new types of ... -
Experimental demonstration of sub-wavelength imaging by left handed metamaterials
(2007)We review the studies conducted in our group concerning electromagnetic properties of metamaterials and photonic crystals with negative effective index of refraction. In particular, we demonstate the true left handed ... -
Ferroelectric based tuneable SRR based metamaterial for microwave applications
(2007)We discuss the possibility of achieving tunable split ring resonators at microwave frequencies. One method is to use varying capacitance values to tune the magnetic resonance frequency. As another method ferroelectric thin ... -
Metamaterial inspired enhanced far-field transmission through a subwavelength nano-hole
(WILEY, 2010-06-02)In the present study, we first demonstrate the polarization and orientation dependent transmission response of split ring resonators at the infrared and visible band. Then, we numerically demonstrate a configuration for ... -
Miniaturization and characterization of metamaterial resonant particles
(2008)This paper is focussed on the miniaturization and characterization of semi-lumped resonators, of interest for the synthesis of metamaterial-based structures such as metamaterial transmission lines, frequency selective ... -
Multi-gap individual and coupled split-ring resonator structures
(Optical Society of American (OSA), 2008)We present a systematic numerical study, validated by accompanied experimental data, of individual and coupled split ring resonators (SRRs) of a single rectangular ring with one, two and four gaps. We discuss the behavior ... -
Observation of negative refraction and negative phase velocity in true left-handed metamaterials
(SPIE - International Society for Optical Engineering, 2005)We report a true left-handed (LH) behavior in a composite metamaterial consisting of periodically arranged split ring resonator (SRR) and wire structures. The magnetic resonance of the SRR structure is demonstrated by ... -
Optimization and tunability of deep subwavelength resonators for metamaterial applications: complete enhanced transmission through a subwavelength aperture
(Optical Society of American (OSA), 2009)In the present work, we studied particle candidates for metamaterial applications, especially in terms of their electrical size and resonance strength. The analyzed particles can be easily produced via planar fabrication ... -
Simulation and micro-fabrication of optically switchable split ring resonators
(Elsevier BV, 2007-10)The effect of conductivity variation as a proposed method for the investigation of photoconductive switching properties of split ring resonators (SRRs) is simulated. Three different systems that are applicable under certain ...
