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…
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…
Theory of superlensing with complex frequency illuminations
Philippe Lalanne, Tong Wu
Recent experiments have demonstrated that the resolution of superlensing slabs can be significantly enhanced with complex frequency illuminations. In this study, we introduce a nov…
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…
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…
