When light interacts with metal nanostructures, it can couple to free-electron excitations near
the metal surface. The electromagnetic resonances associated with these surface plasmons …

Metamaterials are nano-engineered media with designed properties beyond those available
in nature with applications in all aspects of materials science. In particular, metamaterials …

Label-free plasmonic biosensors rely either on surface plasmon polaritons or on localized
surface plasmons on continuous or nanostructured noble-metal surfaces to detect molecular …

Metamaterials are artificial media structured on a size scale smaller than wavelength of
external stimuli, and they can exhibit a strong localization and enhancement of fields, which …

This critical review highlights recent advances in using electronic structure methods to study
surface-enhanced Raman scattering. Examples showing how electronic structure methods …

All-optical signal processing enables modulation and transmission speeds not achievable
using electronics alone,. However, its practical applications are limited by the inherently …

Sensor technology has become increasingly crucial in medical research and clinical
diagnostics to directly detect small numbers of low-molecular-weight biomolecules relevant …

We analyze the optical properties of plasmonic nanorod metamaterials in the ε-near-zero
regime and show, both theoretically and experimentally, that the performance of these …

We review the properties of hyperbolic metamaterials and show that they are promising
candidates as substrates for nanoimaging, nanosensing, fluorescence engineering, and …

Plasmonic nanostructures are extensively used building blocks for engineering optical
materials and device architectures. Plasmonic nanocomposites (pNCs) are an emerging …
