Radial-Component Predominant-Mode Inversion of Rayleigh Waves: Application to DAS-based Site Characterization
Mrinal Bhaumik, Brady R. Cox
Distributed Acoustic Sensing (DAS) has emerged as a transformative technology for near-surface site characterization. When a vertical source is activated along the fiber, DAS measu…

Predominant-Mode Inversion of Surface Waves: Inherently Addressing Inconspicuous Low Frequency Mode Jumps
Mrinal Bhaumik, Brady R. Cox
Inversion of Rayleigh-wave dispersion data is particularly challenging at sites with strong impedance contrasts, where modal energy often transitions smoothly from the fundamental…

Active Sourced Wavefield Modeling for Layered Half-Space
Mrinal Bhaumik, Tarun Naskar
Traditional free vibration-based forward models generate theoretical dispersion curves under the assumption of planar waves, neglecting the influence of the actual source-receiver…
