Inverse design method for periodic and aperiodic metasurfaces based on the adjoint-method: metalens with random-like distributed nano-rods
Kofi Edee, Mauro Antezza, Brahim Guizal
The classical adjoint-based topology optimization (TO) method, based on the use of a random continuous dielectric function as an adjoint variable distribution, is known to be one o…
Inverse design of a 1D dielectric metasurface by topology optimization: fluctuations-trend analysis assisted by a diamond-square algorithm
K. Edee, M. Ben Rhouma, J. -A. Fan +6
We present a topology optimization (TO) method for a 1D dielectric metasurface, coupling the classical trend-fluctuations analysis (FTA) and the diamond-square-algorithm (DSA). In…
Finite Element Method (Chapter from "Gratings: Theory and Numeric Applications")
Guillaume Demésy, Frédéric Zolla, André Nicolet +1
In this chapter, we demonstrate a general formulation of the Finite Element Method allowing to calculate the diffraction efficiencies from the electromagnetic field diffracted by a…
Light wheel buildup using a backward surface mode
Rémi Polles, Antoine Moreau, Gérard Granet
When a guided mode is excited in a dielectric slab coupled to a backward surface wave at the interface between a dielectric and a left-handed medium, light is confined in the struc…
Localization of light in a lamellar structure with left-handed medium : the light wheel
Paul-Henri Tichit, Antoine Moreau, Gérard Granet
The contra-directional coupling between a left-handed monomode waveguide and a right-handed monomode waveguide is rigorously studied using a complex plane analysis. Light is shown…
Enhanced transmission of slit arrays in an extremely thin metallic film
Antoine Moreau, Christophe Lafarge, Nicolas Laurent +2
Horizontal resonances of slit arrays are studied. They can lead to an enhanced transmission that cannot be explained using the single-mode approximation. A new type of cavity reson…
