Super resonance: Breaking the bandwidth limit of resonant modes and its application to flow control
Adam R. Harris, Armin Kianfar, David Roca +3
We report the discovery of super resonance--a new regime of resonant behavior in which a mode's out-of-phase response persists far beyond its classical bandwidth. This effect emerg…

Scatterless interferences: Delay of laminar-to-turbulent flow transition by a lattice of subsurface phonons
Mahmoud I. Hussein, David Roca, Adam R. Harris +1
Wave interference has historically relied on scattering objects placed within the wave domain. Here, we introduce a fundamentally new mechanism: scatterless interference induced by…
