Categorize coalescing quasi-normal modes through far-field scattering patterns
Jingwei Wang, Yuntian Chen, Wei Liu
Resonances in the form of quasi-normal modes (QNMs) for open scattering systems can be generally identified in the far field through peaks of scattering spectra (\textit{e.g.} cros…

Quasi-normal modes empowered coherent control of electromagnetic interactions
Jingwei Wang, Pengxiang Wang, Chaofan Zhang +2
Quasi-normal modes (QNMs) and coherent control of light-matter interactions (through synchronized multiple coherent incident waves) are profound and pervasive concepts in and beyon…

Geometric Phase-Driven Scattering Evolutions
Pengxiang Wang, Yuntian Chen, Wei Liu
Conventional approaches for scattering manipulations rely on the technique of field expansions into spherical harmonics (electromagnetic multipoles), which nevertheless is non-gene…
