Complex modes in an open lossless periodic waveguide

Amgad Abdrabou, Ya Yan Lu

Guided modes of an open periodic waveguide, with a periodicity in the main propagation direction, are Bloch modes confined around the waveguide core with no radiation loss in the t…

Exceptional points of Bloch eigenmodes on a dielectric slab with a periodic array of cylinders

Amgad Abdrabou, Ya Yan Lu

Eigenvalue problems for electromagnetic resonant states on open dielectric structures are non-Hermitian and may have exceptional points (EPs) at which two or more eigenfrequencies…
