Inverse scattering designs of dispersion-engineered single-mode planar waveguides

, 2014
We use an inverse-scattering (IS) approach to design single-mode waveguides with controlled linear and higher-order dispersion. The technique is based on a numerical solution to the Gelfand-Levitan-Marchenko integral equation, for the inversion of ...

Two‐Stage Framework for Precise Measurement of Marsquake Surface Wave Group Velocity Dispersion

Earth and Space Science
Surface wave dispersion analysis is crucial for investigating crustal and mantle structures on Earth and other celestial bodies. On Mars, Rayleigh and Love waves have been detected, with Rayleigh waves exhibiting vertical and radial motion and Love waves

IMAGING DISPERSION CURVE OF DISPERSIVE WAVES USING SHORT-TIME FOURIER TRANSFORM: 2025 MYANMAR EARTHQUAKE M 7.7

JGE
Understanding of Earth's subsurface is crucial for mitigating geological hazards, particularly earthquakes. A key parameter for subsurface characterization is the surface wave dispersion curve, which strongly reflects shear wave velocity (Vs) at various ...

Estimating Fundamental Cross-Section Dispersion from Fixed Event Forecasts [PDF]

A couple of recent papers have shifted the focus towards disagreement of professional forecasters. When dealing with survey data that is sampled at a frequency higher than annual and that includes only fixed event forecasts, e.g.

Non-Contact Ultrasonic Assessment of Corrosion in Steel Specimens

Sensors
Ultrasonic thickness resonance can be effectively used to detect and quantify the level of corrosion in steel nuclear storage containers as well as other corrosion-prone thin-walled structures, such as pipes and storage tanks.
