Tailoring iridescent visual appearance with disordered resonant metasurfaces
A. Agreda, T. Wu, A. Hereu +4
The nanostructures of natural species offer beautiful visual appearances with saturated and iridescent colors and the question arises whether we can reproduce or even create new ap…
Modal analysis of electromagnetic resonators: user guide for the MAN program
T. Wu, D. Arrivault, W. Yan +1
All electromagnetic systems, in particular resonators or antennas, have resonances with finite lifetimes. The associated eigenstates, also called quasinormal modes, are essentially…
QNMnonreciprocal_resonators: an openly available toolbox for computing the QuasiNormal Modes of nonreciprocal resonators
Tong Wu, Philippe Lalanne
QNMnonreciprocal_resonators is an extension (posted in 2021) of the QNMEig solver of the freeware package MAN. It provides a comprehensive presentation of the computation and norma…
