A 1 Tbit/s 53km single channel free-space optical (FSO) link is demonstrated. High bandwidth, high order modulation formats and advanced adaptive optics are utilized. We show that the absence of a nonlinear-Shannon limit in combination with adaptive optics enables record data-transmission with low link failures.
The Double Bounce scattering mechanism is usually compared to the ideal polarimetric response of a metallic dihedral reflector, for instance in the Pauli basis. This is however only valid for perfect metallic targets, perfectly aligned with the sensor. When rotated, the double bounce mechanism gives both a double bounce electromagnetic response (VV...

This paper presents a novel circularly polarized electrically small antenna that has been designed thanks to the Characteristic Mode Analysis (CMA). It is based on the energy compensation between two elements: a non-resonant dipole antenna and a chiral Metamaterial (MTM) in order to achieve a Circular Polarization (CP). First, the two elements are ...

Spectro-polarimetric light-scattering, or merging spectral and polarimetric light-scattering information, is a growing interest in a wide range of scientific fields. Recently, it has been demonstrated how spectral polarimetric light-scattering could be employed to probe microphysical properties of particulate media, for instance mean particle size ...
Spectralons are reference radiometric samples which exhibit a calibrated reflectance. However, in case of low reflectance samples, the degree of polarization (DOP) of scattered light is hard to characterize. Here, an accurate determination of spectralon spatial depolarization is proposed. Based on a spatially resolved polarimetric imaging system, t...
Sense-City facility is a modeled urban test-bed of 250 m2 (25m×10m) located at University Paris-Est (France) that is dedicated to the validation of measurement technologies in the field of urban sustainability [1]. The novel Ground-Penetrating Radar (GPR) test site falls within the purview of Sense-City smart road topic, as networks usually lie bel...
