Exploiting hidden singularity on the surface of the Poincaré sphere
Jinxing Li, Aloke Jana, Yueyi Yuan +3
The classical Pancharatnam-Berry phase, a variant of the geometric phase, arises purely from the modulation of the polarization state of a light beam. Due to its dependence on pola…
Non-local reconfigurable sparse metasurface: Efficient near-field and far-field wavefront manipulations
Vladislav Popov, Badreddine Ratni, Shah Nawaz Burokur +1
In recent years, metasurfaces have shown extremely powerful abilities for manipulation of electromagnetic waves. However, the local electromagnetic response of conventional metasur…
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…
Omega-bianisotropic metasurface for converting a propagating wave into a surface wave
Vladislav Popov, Ana Díaz-Rubio, Viktar Asadchy +4
Although a rigorous theoretical ground on metasurfaces has been established in the recent years on the basis of the equivalence principle, the majority of metasurfaces for converti…
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…
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…
Direct dark mode excitation by symmetry matching of a single-particle based metasurface
Shah Nawaz Burokur, Anatole Lupu, André de Lustrac
This paper makes evidence for direct dark mode excitation mechanism in a metasurface structure. The dark mode excitation mechanism is entirely determined by structures' symmetry an…
Design and experimental demonstration of a high-directive emission with optical transformations
Tichit Paul-Henri, Shah Nawaz Burokur, Dylan Germain +1
With the explosion of wireless networks and automotive radar systems, there is an acute need for new materials and technologies that would not only minimize the size of these devic…
Waveguide taper engineering using coordinate transformation technology
Paul-Henri Tichit, Shah Nawaz Burokur, Andre de Lustrac
Spatial coordinate transformation is a suitable tool for the design of complex electromagnetic structures. In this paper, we define three spatial coordinate transformations which s…
Ultra directive antenna via transformation optics
Paul-Henri Tichit, Shah Nawaz Burokur, Andre de Lustrac
Spatial coordinate transformation is used as a reliable tool to control electromagnetic fields. In this paper, we derive the permeability and permittivity tensors of a metamaterial…
