A continuous family of Exact Dispersive Quasi-Normal Modal (DQNM) Expansions for dispersive photonic structures
Minh Duy Truong, André Nicolet, Guillaume Demésy +1
In photonics, Dispersive Quasi-Normal Modes (DQNMs) refer to optical resonant modes, solutions of spectral problems associated with Maxwell's equations for open photonic structures…
Quasinormal mode solvers for resonators with dispersive materials
P. Lalanne, W. Yan, A. Gras +16
Optical resonators are widely used in modern photonics. Their spectral response and temporal dynamics are fundamentally driven by their natural resonances, the so-called quasinorma…
Photonics in highly dispersive media: The exact modal expansion
Frédéric Zolla, André Nicolet, Guillaume Demésy
We present exact modal expansions for photonic systems including highly dispersive media. The formulas, based on a simple version of the Keldysh theorem, are very general since bot…
Scattering matrix of arbitrarily shaped objects: Combining Finite Elements and Vector Partial Waves
Guillaume Demésy, Brian Stout, Jean-Claude Auger
We demonstrate the interest of combining Finite Element calculations with the Vector Partial Wave formulation (used in T-matrix and Mie theory) in order to characterize the electro…
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…
