Enhanced Sensitivity of Degenerate System Made of Two Unstable Resonators Coupled by Gyrator Operating at an Exceptional Point
Kasra Rouhi, Alireza Nikzamir, Alexander Figotin +1
We demonstrate that a circuit comprising two unstable LC resonators coupled via a gyrator supports an exceptional point of degeneracy (EPD) with purely real eigenfrequency. Each of…
Experimental Demonstration of a New Oscillator Concept Based on Degenerate Band Edge in Microstrip Circuit
Dmitry Oshmarin, Ahmed F. Abdelshafy, Alireza Nikzamir +2
The first experimental demonstration of an oscillator based on a periodic, resonant microstrip circuit with a degenerate band edge (DBE) is presented. The DBE is a fourth-order exc…
Exceptional Degeneracy in a Waveguide Periodically Loaded with Discrete Gain and Radiation Loss Elements
Ahmed F. Abdelshafy, Tarek Mealy, Ehsan Hafezi +2
We demonstrate that a periodic waveguide comprising of uniform lossless segments together with discrete gain and radiating elements supports exceptional points of degeneracy (EPDs)…
