Numerical Simulation and Observational Data Analysis of Mesoscale Eddy Effects on Surface Waves in the South China Sea

Remote Sensing, 2022
Surface current velocities of mesoscale eddies have a unique annular structure, which can inevitably influence surface wave properties and energy distribution.

Temperature-controlled acoustic surface waves

New Journal of Physics, 2016
Conventional approaches to the control of acoustic waves propagating along boundaries between fluids and hard grooved surfaces are limited to the manipulation of surface geometry.

S1222a—The Largest Marsquake Detected by InSight

Geophysical Research Letters, 2023
NASA's InSight has detected a large magnitude seismic event, labeled S1222a. The event has a moment magnitude of MWMa4.7, with five times more seismic moment compared to the second largest event.

Optical surface waves in periodic layered media [PDF]

, 1978
A generalized analysis of wave propagation in periodic layered media is applied to the special case of optical surface waves. These waves, confined to the interface between a periodic layered medium and a homogeneous medium, are formally analogous to ...

Multiple Bloch surface wave excitation with gratings

Journal of the European Optical Society-Rapid Publications
We study the coupling of a finite number of Bloch Surface Waves (BSWs) propagating in different directions at the surface of a dielectric multilayer. These surface waves arise from a set of diffraction orders associated to a grating on the bottom surface

Electromagnetic surface waves on a conducting cylinder

, 2015
We study propagation of electromagnetic surface waves on a metal-air interface in the case when the wave frequency is below the plasma frequency. We derive a reduced wave equation for a metal cylinder with a given radius of curvature.

Classification of River Sediment Fractions in a River Segment including Shallow Water Areas Based on Aerial Images from Unmanned Aerial Vehicles with Convolution Neural Networks

Remote Sensing, 2023
Riverbed materials serve multiple environmental functions as a habitat for aquatic invertebrates and fish. At the same time, the particle size of the bed material reflects the tractive force of the flow regime in a flood and provides useful information ...

Surface waves in granular phononic crystals

, 2015
The existence of surface elastic waves at a mechanically free surface of granular phononic crystals is studied. The granular phononic crystals are made of spherical particles distributed periodically on a simple cubic lattice.
