Broadband cloaking for flexural waves
Ahmad Zareei, Mohammad-Reza Alam
The governing equation for elastic waves in flexural plates is not form invariant, and hence designing a cloak for such waves faces a major challenge. Here, we present the design o…
Sensitivity of Internal Wave Energy Distribution over Seabed Corrugations to Adjacent Seabed Features
F. Karimpour, A. Zareei, M. -R. Alam
Here we show that the distribution of internal gravity waves energy over a patch of seabed corrugations strongly depends on the "distance" of the patch to adjacent seafloor feature…
Oblique internal-wave chain resonance over seabed corrugations
Louis-Alexandre Couston, Yong Liang, Mohammad-Reza Alam
We show that monochromatic long-crested corrugations on an otherwise flat seafloor can coherently scatter the energy of an oblique incident internal wave to multiple multi-directio…
Inherently Unstable Internal Gravity Waves due to Resonant Harmonic Generation
Y. Liang, Ahmad Zareei, M. -R. Alam
Here we show that there exist internal gravity waves that are inherently unstable, that is, they cannot exist in nature for a long time. The instability mechanism is a one-way (irr…
