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…
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…
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…
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…
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…
