Electromagnetically Induced Transparency and Absorption in Metamaterials: The Radiating Two-Oscillator Model and Its Experimental Confirmation
Philippe Tassin, Lei Zhang, Rongkuo Zhao +3
Several classical analogues of electromagnetically induced transparency in metamaterials have been demonstrated. A simple two-resonator model can describe their absorption spectrum…
A comparison of graphene, superconductors and metals as conductors for metamaterials and plasmonics
Philippe Tassin, Thomas Koschny, Maria Kafesaki +1
Recent advancements in metamaterials and plasmonics have promised a number of exciting applications, in particular at terahertz and optical frequencies. Unfortunately, the noble me…
Effective material parameter retrieval for thin sheets: theory and application to graphene, thin silver films, and single-layer metamaterials
Philippe Tassin, Thomas Koschny, Costas M. Soukoulis
An important tool in the field of metamaterials is the extraction of effective material parameters from simulated or measured scattering parameters of a sample. Here we discuss a r…
Optical metamaterials with different metals
Nian-Hai Shen, Thomas Koschny, Maria Kafesaki +1
We investigate the influence of different metals on the electromagnetic response of fishnet metamaterials in the optical regime.We found, instead of using a Drude model, metals wit…
Discontinuous design of negative index metamaterials based on mode hybridization
Nian-Hai Shen, Lei Zhang, Thomas Koschny +3
An electric inductor-capacitor (ELC) resonator provides a series of electrical resonances and a pair of ELC resonators leads to the split of each resonance into two modes, i.e., ma…
Effects of free-electron-laser field fluctuations on the frequency response of driven atomic resonances
G. M. Nikolopoulos, P. Lambropoulos
We study the effects of field fluctuations on the total yields of Auger electrons, obtained in the excitation of neutral atoms to a core-excited state by means of short-wavelength…
