Internal optical forces in plasmonic nanostructures

Olivier Martin, Raziman Thottungal Valapu

We present a computational study of the internal optical forces arising in plasmonic gap antennas, dolmen structures and split rings. We find that very strong internal forces perpendicular to the propagation direction appear in these systems. These interna ...

Acoustic Metasurface

Hervé Lissek, Sami Driss Karkar, Seyyed Hussein Seyyed Esfahlani

Metasurfaces have gained fame for their ability to control the transmitted and reflected phase front of waves. Here, we introduce a reflector-type acoustic metasurface designed in such a way to control the phase front of reflected sound waves. The proposed ...

An innovative class of coupling gratings for efficiently redirecting light beams is described. They are based on symmetric binary gratings equipped with an asymmetric high refractive index coating. This kind of structure exhibits a grating blaze effect and ...

Near-field imaging

Libo Yu

Bloch surface waves (BSWs) are surface electromagnetic waves excited at the interface between a truncated periodic dielectric multilayer and a surrounding medium. This particular solution to the Maxwell equations in stratified media has been known since th ...

The influence of stress on the polarization extinction ratio (PER) when solderjet-bumping a bow-tie polarization-maintaining fiber (PMF) to a V-grooved ceramic substrate is experimentally evaluated. Throughout this paper, the linear polarization of the cou ...

Institute of Electrical and Electronics Engineers2013

In this work we present a simple reconfigurable reflectarray (RRA) unit cell general topology and implementation, which allows the independent control of the phase and polarization of the reflected electromagnetic wave. The 1-bit phase control (with 180 de ...

High-brightness polarized light-emitting diodes

Elison de Nazareth Matioli

Light-emitting diodes are becoming the alternative for future general lighting applications, with huge energy savings compared to conventional light sources owing to their high efficiency and reliability. Polarized light sources would largely enhance the e ...
