A deep dive into Tollmien-Schlichting wave control via passive wall deformations: The battle between local and downstream stabilization, lessons learned, and implications for phononic subsurfaces
H. Yousef, H. Hassan, I. Roy +3
A decade ago, a landmark study on flow control via subsurface phonons transformed our understanding of fluid-structural interactions, compelling us to reimagine ways by which to su…

A blueprint for truncation resonance placement in elastic diatomic lattices with unit cell asymmetry
Hasan B. Al Ba'ba'a, Hosam Yousef, Mostafa Nouh
Elastic periodic lattices act as mechanical filters of incident vibrations. By and large, they forbid wave propagation within bandgaps and resonate outside them. However, they ofte…
