Exceptional points for resonant states on parallel circular dielectric cylinders
Amgad Abdrabou, Ya Yan Lu
Exceptional points (EPs) are special parameter values of a non-Hermitian eigenvalue problem where eigenfunctions corresponding to a multiple eigenvalue coalesce. In optics, EPs are…

Indirect link between resonant and guided modes on uniform and periodic slabs
Amgad Abdrabou, Ya Yan Lu
A uniform or periodic dielectric slab can serve as an optical waveguide for which guided modes are important, and it can also be used as a diffraction structure for which resonant…
