Metasurfaces for Far-Field Radiation Pattern Correction of Antennas under Dielectric Seamed-Radomes
Autor: Riccardo Cacocciola, Badreddine Ratni, Nicolas Mielec, Emmanuel Mimoun, Shah Nawaz Burokur
Publikováno v: Materials, Vol 15, Iss 2, p 665 (2022)
A high-index dielectric radome seam is camouflaged with respect to a low-index dielectric radome panel by tuning the seam with carefully engineered metasurfaces. A transmission-line approach is used to model the metasurface-tuned seam and analyticall

Camouflaging a High-Index Dielectric Scatterer with Metasurfaces
Autor: Emmanuel Mimoun, Badreddine Ratni, N. Mielec, Shah Nawaz Burokur, Riccardo Cacocciola
Publikováno v: 2021 Fifteenth International Congress on Artificial Materials for Novel Wave Phenomena (Metamaterials).
High-index dielectric mechanical pieces constitute an important source of signal losses in radio frequency systems due to scattering effects. In this study, we propose to camouflage a dielectric scatterer by tuning it with buried metasurfaces. The im

Metasurface-tuning: A camouflaging technique for dielectric obstacles
Autor: Riccardo Cacocciola, Badreddine Ratni, Emmanuel Mimoun, Shah Nawaz Burokur, Nicolas Mielec
Publikováno v: Journal of Applied Physics. 129:124902
We present the concept of metasurface-tuning as a solution to reduce spurious scattering from parasitic dielectric objects. By burying metasurfaces in the dielectric volume, it is possible to control the scattering behavior of the parasitic object an

We study experimentally the equilibrium phase diagram of a spin 1 Bose-Einstein condensate with antiferromagnetic interactions, in a regime where spin and spatial degrees of freedom are decoupled. For a given total magnetization mz, we observe for lo

We demonstrate a frequency-stabilized, all-solid laser source at 589 nm with up to 800 mW output power. The laser relies on sum-frequency generation from two laser sources at 1064 nm and 1319 nm through a PPKTP crystal in a doubly resonant cavity. We
