Modal analysis of electromagnetic resonators: MAN software expansion to 2D materials and coupled systems
Thomas Christopoulos, Tong Wu, P. Lalanne
This work presents an updated version of the previously released freeware MAN (Modal Analysis of Nanoresonators) [Comput Phys Commun 284, 108627 (2023)], a software package designe…
Metasurface Engineering with Tantalum Pentoxide-Coated Microspheres: Tailoring Optical Resonances and Enhancing Local Density of States
Alexandra Fălamaş, Ana Maria M. Gherman, Renaud Vallée +1
Hexagonally-packed polystyrene microsphere monolayers coated with tantalum pentoxide (TaO) form scalable dielectric metasurfaces that support tunable photonic resonances an…
Rigorous electromagnetic quasinormal-mode method made easy for users
Tong Wu, Philippe Lalanne
Full-wave numerical methods based on quasinormal modes (QNMs) offer valuable physical insights and computational efficiency for analyzing electromagnetic resonators. However, despi…
Gradient-based optimization of scatterer arrangements based on the T-matrix method
Nigar Asadova, Jan David Fischbach, Renaud Vallée +6
The demand for inverse design is increasing as the ability to fabricate sub-10 nm features expands the design space by orders of magnitude. Efficient inverse design benefits from d…
From Light Diffusion to Photocatalytic Rates: Compact Scaling Laws for Strongly Scattering Porous Slabs
Renaud A. L. Vallée, Rénal Backov
Light transport in strongly scattering porous photocatalytic materials governs the spatial distribution of absorbed photons and therefore the generation of charge carriers driving…
Dissipative Coupling in Photonic and Plasmonic Resonators
Tong Wu, Philippe Lalanne
The rapid progress of nanophotonics demands theoretical frameworks capable of predicting the resonant behavior of complex systems comprising constituents of varying nature, operati…
