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…
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…
Emergent scattering regimes in disordered metasurfaces near critical packing
Miao Chen, Adrian Agreda, Tong Wu +3
Disordered metasurfaces provide a versatile platform for harnessing near- and far-field scattered light. Most research has focused on either particulate topologies composed of indi…
Quasinormal mode as a foundational framework for all electromagnetic Fano resonances
Mikhail Bochkarev, Nikolay Solodovchenko, Kirill Samusev +3
Fano profiles are observed across various fields of wave physics. They emerge from interference phenomena and are quantified by the asymmetry parameter q. In optics, q is usually c…
Designing electromagnetic resonators with quasinormal modes
Tong Wu, Philippe Lalanne
Micro- and nanoresonators, which enable light trapping in small volumes for extended durations, play a crucial role in modern photonics. The optical response of these resonators is…
On the Exact Maxwell evolution equation of resonator dynamics
Tong Wu, Rachid Zarouf, Philippe Lalanne
In a recent publication [Opt. Express 32, 20904 (2024)], the accuracy of the main evolution equation that governs resonator dynamics in the coupled-mode theory (CMT) was questioned…
Discussions on the spatial exponential growth of electromagnetic quasinormal modes
Tong Wu, Jose Luis Jaramillo, Philippe Lalanne
The temporal response of open systems is marked by damped oscillations. These oscillations, often referred to as ringings, are the signature of the decay of quasinormal modes (QNMs…
Exact Maxwell evolution equation of resonators dynamics: temporal coupled-mode theory revisited
Tong Wu, Philippe Lalanne
Despite its widespread significance, the temporal coupled-mode theory (CMT) lacks a foundational validation based on electromagnetic principles and stands as a phenomenological the…
Minireview on Disordered Optical Metasurfaces
P. Lalanne, A. Dmitriev, C. Rockstuhl +2
The use of coherent wave phenomena to enhance device performance is a cornerstone of modern optics. In juxtaposition to (locally) periodic metasurfaces, their disordered counterpar…
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…
Normalization, orthogonality and completeness of quasinormal modes of open systems: the case of electromagnetism
C. Sauvan, T. Wu, R. Zarouf +2
The scattering of electromagnetic waves by resonant systems is determined by the excitation of quasinormal modes (QNMs), i.e., the eigenmodes of the system. This Review addresses t…
Decomposing the scattered field of two-dimensional metaatoms into multipole contributions
J. Petschulat, J. Yang, C. Menzel +6
We introduce a technique to decompose the scattered near field of two-dimensional arbitrary metaatoms into its multipole contributions. To this end we expand the scattered field up…
