TL;DR: These experiments directly confirm the predictions of Maxwell's equations that n is given by the negative square root ofɛ·μ for the frequencies where both the permittivity and the permeability are negative.

TL;DR: A composite medium, based on a periodic array of interspaced conducting nonmagnetic split ring resonators and continuous wires, that exhibits a frequency region in the microwave regime with simultaneously negative values of effective permeability and permittivity varepsilon(eff)(omega).

TL;DR: In this article, the authors analyzed the reflection and transmission coefficients calculated from transfer matrix simulations on finite lengths of electromagnetic metamaterials, to determine the effective permittivity and permeability.

TL;DR: In this paper, the authors present experimental data, numerical simulations, and analytical transfer-matrix calculations for a two-dimensional isotropic, left-handed metamaterial (LHM) at X-band microwave frequencies.

TL;DR: In this paper, an experimental darkfield microscope study of the dependence of the plasmon resonance spectrum of individual silver nanoparticles on the local index of refraction is presented. But the results are consistent with experiments performed on ensembles of similar nanoparticles and suggest that individual nanoparticles may be utilized in biosensing applications where currently ensemble are being investigated.
