Template assisted dewetting of optical glasses for large area, flexible and stretchable all dielectric metasurfaces

Fabien Sorin, Wei Yan, Alexis Gérald Page, Yunpeng Qu, Louis Marie Philippe Martin-Monier, Arthur Le Bris

We propose for the first time template-assisted dewetting of high-index chalcogenide glasses for low-cost manufacturing of all-dielectric metasurfaces on large-area flexible and stretchable substrates. ...

Free-electron-laser coherent diffraction images of individual drug-carrying liposome particles in solution

Giorgio Margaritondo, Ying Chen, Ke Peng

Using the excellent performances of a SACLA (RIKEN/HARIMA, Japan) X-ray free electron laser (X-FEL), coherent diffraction imaging (CDI) was used to detect individual liposome particles in water, with or without inserted doxorubicin nanorods. This was possi ...

Synthesis and Analysis of Linear and Nonlinear Bianisotropic Metasurfaces

Olivier Martin, Karim Achouri, Christophe Caloz

We present our recent progress pertaining to the synthesis and analysis of bianisotropic linear and nonlinear metasurfaces. These developments are based on the generalized sheet transition conditions (GSTCs), which provide a very complete and general metho ...

From model to radar variables: a new forward polarimetric radar operator for COSMO

Alexis Berne, Daniel Wolfensberger

In this work, a new forward polarimetric radar operator for the COSMO numerical weather prediction (NWP) model is proposed. This operator is able to simulate measurements of radar reflectivity at horizontal polarization, differential reflectivity as well a ...

Plasmonic and Dielectric Metasurfaces for Molecular Specific Mid-IR Biosensors

Hatice Altug

Mid-infrared spectrum is powerful for biosensing application, as it encompasses the molecular vibrations that uniquely identify the biochemicals. Here, we will present our contributions using metal, graphene and dielectric based Mid-IR nanophotonics. ...

Wavevector-Selective Nonlinear Plasmonic Metasurfaces

Olivier Martin, Jérémy Butet, Chen Yan, Kuang-Yu Yang

Electromagnetic metasurfaces with strong non- linear responses and angular selectivity could o ff er many new avenues for designing ultrathin optics components. We investigated the optical second harmonic generation from plasmonic metasurfaces composed of ...

Small-Scale Variability of the Raindrop Size Distribution and Its Effect on Areal Rainfall Retrieval

Alexis Berne, Timothy Hugh Raupach

The drop size distribution (DSD) describes the microstructure of liquid precipitation. The high variability of the DSD reflects the variety of microphysical processes controlling raindrop properties and affects the retrieval of rainfall. An analysis of the ...

Acoustic carpet cloak based on an ultrathin metasurface

Juan Ramon Mosig, Hervé Lissek, Sami Driss Karkar, Seyyed Hussein Seyyed Esfahlani

An acoustic metasurface carpet cloak based on membrane-capped cavities is proposed and investigated numerically. This design has been chosen for allowing ultrathin geometries, although adapted to airborne sound frequencies in the range of 1 kHz (λ≈30 cm), ...

Variability of the raindrop size distribution across scales in Mediterranean rainfall

Timothy Hugh Raupach

Measurement of rain is made difficult by the high variability of the precipitation process, down to raindrop scale. Point measurements are generally accurate, but their lack of spatial representativeness is a significant limitation. Weather radars indirect ...
