TL;DR: A bilayer of materials for which not all of the principal elements of the permeability and permittivity tensors have the same sign can transfer a field distribution from one side to the other, including near fields, without requiring internal exponentially growing waves.

TL;DR: It is proposed that PRPs can replace or complement established labels, such as those based on radioactivity, fluorescence, chemiluminescence, or enzymatic/colorimetric detection that are used routinely in biochemistry, cell biology, and medical diagnostic applications.

TL;DR: In this paper, the orientation of dipole emitters in nanogaps plays a vital role in spontaneous emission enhancement factors of greater than 1,000, the largest observed to date.

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.
