Specular Reflection and Transmission of Electromagnetic Waves by Disordered Metasurfaces
Planar, disordered assemblies of small particles incorporated in layered media—sometimes called “disordered metasurfaces” in the recent literature—are becoming widespread in optics and photonics. Their ability...

Open AccessVortex Laser based on III-V semiconductor metasurface: direct generation of coherent Laguerre-Gauss modes carrying controlled orbital angular momentum
The generation of a coherent state, supporting a large photon number, with controlled orbital-angular-momentum L = ħl (of charge l per photon) presents both fundamental and technological challenges: we demonstrat...

Comprehensive Surface-Wave Description for the Nano-scale Energy Concentration with Resonant Dipole Antennas
Resonant optical dipole nano-antennas allow giant field enhancement within nano-gaps. To show how the energy of external illumination waves is delivered and concentrated in nano-gaps, we build up a model by co...

Waves on Subwalength Metallic Surfaces: A Microscopic View Point
At a microscopic level, the electromagnetic properties of subwavelength metallic surfaces are due to two kinds of elementary distinct waves, the surface plasmon polaritons and the quasi-cylindrical waves. Thes...
