Experimental Demonstration of Degenerate Band Edge in Metallic Periodically-Loaded Circular Waveguide
Mohamed A. K. Othman, Xuyuan Pan, Georgios Atmatzakis +2
We experimentally demonstrate for the first time the degenerate band edge (DBE) condition, namely the degeneracy of four Bloch modes, in loaded circular metallic waveguides. The fo…
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…
Solution of Cavity Resonance and Waveguide Scattering Problems Using the Eigenmode Projection Technique
Mamdouh H. Nasr, Mohamed A. K. Othman, Islam A. Eshrah +1
An eigenmode projection technique (EPT) is developed and employed to solve problems of electromagnetic resonance in closed cavities and scattering from discontinuities in guided-wa…
Theory of Double Ladder Lumped Circuits With Degenerate Band Edge
Jeff Sloan, Mohamed A. K. Othman, Filippo Capolino
A conventional periodic LC ladder circuit forms a transmission line that has a regular band edge between a pass and a stop band. Here for the first time we develop the theory of si…
