Coupling Methodology for Studying the Far Field Effects of Wave Energy Converter Arrays over a Varying Bathymetry

open access: yesEnergies, 2018
For renewable wave energy to operate at grid scale, large arrays of Wave Energy Converters (WECs) need to be deployed in the ocean. Due to the hydrodynamic interactions between the individual WECs of an array, the overall power absorption and surrounding

Quantifying the ultimate limit of plasmonic near-field enhancement

open access: yesNature Communications
Quantitatively probing the ultimate limit of near-field enhancement around plasmonic nanostructures remains elusive, despite more than five decades since the discovery of surface-enhanced Raman scattering.

Novel Method to Improve the Signal to Noise Ratio in the Far-field Results Obtained from Planar Near Field Measurements. [PDF]

open access: yes, 2010
A method to reduce the noise power in far-field pattern without modifying the desired signal is proposed. Therefore, an important signal-to-noise ratio improvement may be achieved.

Near-field Nanoscopy of Terahertz Polaritons with Quantitative Dielectric Mapping [PDF]

open access: yes, 2021
Terahertz waves find broad use in physics, chemistry, and engineering for sensing applications. However, most experiments operate in the far-field, which precludes the observation of nanoscale features that affect the material response.

Vectorial near-field coupling [PDF]

open access: yesNature Nanotechnology, 2019
The coherent exchange of optical near fields between two neighboring dipoles plays an essential role for the optical properties, quantum dynamics and thus for the function of many naturally occurring and artificial nanosystems. These interactions are inherently short-ranged, extending over a few nanometers only, and depend sensitively on relative ...
