20 08 A metamaterial analog of electromagnetically induced transparency
We present a new type of electromagnetic planar metamaterial that exhibit strong dispersion at a local minimum of losses and is believed to be the first metamaterial analog of electromagnetically induced transparency. We demonstrate that pulses propagating through such metamaterials experience considerable delay, whereas the thickness of the structure along the direction of wave propagation is ...
متن کاملClassical analog of electromagnetically induced transparency
Imagine a medium that strongly absorbs a light beam of a certain frequency. Add a second light source, with a frequency that would also be absorbed by the medium, and the medium becomes transparent to the first light beam. This curious phenomenon is called electromagnetically induced transparency ~EIT!. It usually takes place in vapors of threelevel atoms. The light sources are lasers that driv...
متن کاملSlow-light plasmonic metamaterial based on dressed-state analog of electromagnetically induced transparency.
We consider a simple configuration for realizing one-dimensional slow-light metamaterials with large bandwidth-delay products using stub-shaped Fabry-Perot resonators as building blocks. Each meta-atom gives rise to large group indices because of a classical analog of the dressed-state picture of electromagnetically induced transparency. By connecting up to eight meta-atoms, we find bandwidth-d...
متن کاملElectromagnetically Induced Transparency in Symmetric Planar Metamaterial at THz Wavelengths
We report the experimental observation and the evidence of the analogue of electromagnetically-induced transparency (EIT) in a symmetric planar metamaterial. This effect has been obtained in the THz range thanks to a destructive Fano-interference between the two first modes of an array of multi-gap split ring resonators deposited on a silicon substrate. This structure is a planar thin film mate...
متن کاملPolarization and incidence insensitive dielectric electromagnetically induced transparency metamaterial.
In this manuscript, we demonstrate numerically classical analogy of electromagnetically induced transparency (EIT) with a windmill type metamaterial consisting of two dumbbell dielectric resonator. With proper external excitation, dielectric resonators serve as EIT bright and dark elements via electric and magnetic Mie resonances, respectively. Rigorous numerical analyses reveal that dielectric...
