Effect of top metallic contacts on energy conversion performances for near-field thermophotovoltaics
Youssef Jeyar, Kevin Austry, Minggang Luo +5
The design of metallic contact grids on the front side of thermophotovoltaic cells is critical since it can cause significant optical and electrical resistive losses, particularly…
Near-field radiative heat transfer between shifted graphene gratings
Minggang Luo, Youssef Jeyar, Brahim Guizal +1
We examine the near-field radiative heat transfer between finite-thickness planar fused silica slabs covered with graphene gratings, through the utilization of the Fourier modal me…
Electromagnetic scattering by a partially graphene-coated dielectric cylinder : efficient computation and multiple plasmonic resonances
Youssef Jeyar, Mauro Antezza, Brahim Guizal
We present a numerical approach for the solution of electromagnetic scattering from a dielectric cylinder partially covered with graphene. It is based on a classical Fourier-Bessel…
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…
Coupling between subwavelength nano-slits lattice modes and metal-insulator-graphene cavity modes: A semi-analytical model
Kofi Edee, Maha Benrhouma, Mauro Antezza +2
We present a semi-analytical model of the resonance phenomena occurring in a hybrid system made of a 1D array of periodic subwavelength slits deposited on an insulator/graphene lay…
