Conformal sparse metasurfaces for wavefront manipulation
Vladislav Popov, Shah Nawaz Burokur, Fabrice Boust
While flat metasurfaces are intensively studied, theoretical modelling of conformal metasurfaces appears to be exceptionally challenging where it demands accurate analysis of the m…
Beamforming with metagratings at microwave frequencies: design procedure and experimental demonstration
Vladislav Popov, Fabrice Boust, Shah Nawaz Burokur
As opposed to metasurfaces, metagratings represent themselves sparse arrangements of scatterers. Established rigorous analytical models allow metagratings to overcome performance o…
Designing Metagratings Via Local Periodic Approximation: From Microwaves to Infrared
Vladislav Popov, Marina Yakovleva, Fabrice Boust +3
Recently, metamaterials-inspired diffraction gratings (or metagratings) have demonstrated unprecedented efficiency in wavefront manipulation by means of relatively simple structure…
Constructing the Near field and Far field with Reactive Metagratings: Study on the Degrees of Freedom
Vladislav Popov, Fabrice Boust, Shah Nawaz Burokur
We report that metamaterial-inspired one-dimensional gratings (or metagratings) can be used to control nonpropagating diffraction orders as well as propagating ones. By accurate en…
On the asymptotics of Maronna's robust PCA
Gordana Draskovic, Arnaud Breloy, Frederic Pascal
The eigenvalue decomposition (EVD) parameters of the second order statistics are ubiquitous in statistical analysis and signal processing. Notably, the EVD of robust scatter -es…
Controlling diffraction patterns with metagratings
V. Popov, F. Boust, S. N. Burokur
In this study we elaborate on the recent concept of metagratings proposed in Ra'di et al. [Phys. Rev. Lett. 119, 067404 (2017)] for efficient manipulation of reflected waves. Basic…
