Exceptional points of degeneracy and -symmetry in photonic coupled chains of scatterers
Mohamed A. K. Othman, Vincenzo Galdi, Filippo Capolino
We demonstrate the existence of exceptional points of degeneracy (EPD) of periodic eigenstates in non-Hermitian coupled chains of dipolar scatterers. Guided modes supported by thes…

Theory of Exceptional Points of Degeneracy in Uniform Coupled-Waveguides and Balance of Gain and Loss
Mohamed A. K. Othman, Filippo Capolino
We present a transmission line theory of exceptional points of degeneracy (EPD) in coupled-mode guiding structures, i.e., a theory that illustrates the characteristics of coupled e…
