Phys. Rev. Lett. 104, 104503 (2010), 2010 We report the first observation of extreme wave events (rogue waves) in parametrically driven capillary waves. Rogue waves are observed above a certain threshold in forcing. Above this threshold, frequency spectra broaden and develop exponential tails.

A Microring Resonator Based Negative Permeability Metamaterial Sensor
Sensors, 2011 Metamaterials are artificial multifunctional materials that acquire their material properties from their structure, rather than inheriting them directly from the materials they are composed of, and they may provide novel tools to significantly enhance ...

Symmetric waves are traveling waves for a shallow water equation for surface waves of moderate amplitude [PDF]
, 2016 Following a general principle introduced by Ehrnstr\"{o}m et.al. we prove that for an equation modeling the free surface evolution of moderate amplitude waves in shallow water, all symmetric waves are traveling waves.

Spatially Tracking Wave Events in Partitioned Numerical Wave Model Outputs [PDF]
, 2018 Numerical wave models can output partitioned wave parameters at each grid point using a spectral partitioning technique. Because these wave partitions are usually organized according to the magnitude of their wave energy without considering the coherence of wave parameters in space, it can be difficult to observe the spatial distributions of wave field

First Evidence of Coexisting EIT Wave and Coronal Moreton Wave from SDO/AIA Observations [PDF]
2011, ApJ, 732, L20, 2011 "EIT waves" are a globally propagating wavelike phenomenon. They were often interpreted as a fast-mode magnetoacoustic wave in the corona, despite various discrepancies between the fast-mode wave model and observations. To reconcile these discrepancies, we once proposed that "EIT waves" are apparent propagation of the plasma compression due to ...
