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…
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…
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…
