Third Order Modal Exceptional Degeneracy in Waveguides with Glide-Time Symmetry

Farshad Yazdi, Tarek Mealy, Alireza Nikzamir +2

The dispersion of a three-way waveguide is engineered to exhibit exceptional modal characteristics. Two coupled waveguides with Parity-Time (PT) symmetry have been previously demon…

Triple Ladder Lumped Circuit with Sixth Order Modal Exceptional Degeneracy

Farshad Yazdi, Alireza Nikzamir, Tarek Mealy +2

We introduce a circuit topology based on a simple triple-ladder circuit realized with lumped reactive components that provides a sixth order degenerate band-edge (6DBE). The 6DBE i…

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…

A New Amplification Regime for Traveling Wave Tubes with Third Order Modal Degeneracy

Farshad Yazdi, Mohamed A. K. Othman, Mehdi Veysi +2

Engineering of the eigenmode dispersion of slow-wave structures (SWSs) to achieve desired modal characteristics, is an effective approach to enhance the performance of high power t…

Oscillator Based on Lumped Double Ladder Circuit with Band Edge Degeneracy

Dmitry Oshmarin, Farshad Yazdi, Mohamed A. K. Othman +4

An oscillator design based on a periodic, double ladder resonant circuit is proposed. The circuit exhibits a degenerate band edge (DBE) in the dispersion diagram of its phase-frequ…
