Exceptional points of degeneracy in traveling wave tubes
Alexander Figotin
Traveling wave tube (TWT) is a powerful vacuum electronic device used to amplify radio-frequency (RF) signals with numerous applications, including radar, television and telephone…
Perturbations of circuit evolution matrices with Jordan blocks
Alexander Figotin
In our prior studies we synthesized special circuits possessing evolution matrices that involve nontrivial Jordan blocks and the corresponding degenerate eigenfrequencies. The dege…
Circuit Synthesis based on Prescribed Lagrangian
Alexander Figotin
We advance here an algorithm of a synthesis of an electric circuit based on prescribed quadratic Lagrangian. That is the circuit evolution equations are equivalent to the relevant…
Synthesis of lossless electric circuits based on prescribed Jordan forms
Alexander Figotin
We advance here an algorithm of the synthesis of lossless electric circuits such that their evolution matrices have the prescribed Jordan canonical forms subject to natural constra…
Exceptional Points of Degeneracy Directly Induced by Space-Time Modulation of a Single Transmission Line
Kasra Rouhi, Hamidreza Kazemi, Alexander Figotin +1
We demonstrate how exceptional points of degeneracy (EPDs) are induced in a single transmission line (TL) directly by applying periodic space-time modulation to the per-unit-length…
