Experimental Demonstration of Sixth Order Degenerate Band Edge in Coupled Microstrip Waveguides
Farshad Yazdi, Dmitry Oshmarin, Tarek Mealy +3
We show the physical realization and experimental demonstration of an exceptional point of 6th order degeneracy in a triple ladder (or three-way) microwave waveguide realized using…

Exceptional Points of Degeneracy in Periodic Coupled Waveguides and the Interplay of Gain and Radiation Loss: Theoretical and Experimental Demonstration
Ahmed F. Abdelshafy, Mohamed A. K. Othman, Dmitry Oshmarin +2
We present a novel paradigm for dispersion engineering in coupled transmission lines (CTLs) based on exceptional points of degeneracy (EPDs). We develop a theory for fourth-order E…
