Optical wave splitting due to transient energy convection between the pump and Stokes waves in stimulated Brillouin scattering [PDF]

open access: yesarXiv, 2017
In this paper, we prove theoretically that both the stimulated Stokes scattering and its reverse process can occur simultaneously for the light and acoustic waves at different points of the medium, resulting in transient and alternate energy flow between the pump and Stokes waves in the stimulated Brillouin scattering.

Human Sensation of Transcranial Electric Stimulation. [PDF]

open access: yes, 2019
Noninvasive transcranial electric stimulation is increasingly being used as an advantageous therapy alternative that may activate deep tissues while avoiding drug side-effects. However, not only is there limited evidence for activation of deep tissues by

Fabrication and Characterization of MWCNTs Decorated ZnO Nanograins Based Sensor for Enhanced Performance Toward CO2 Gas

open access: yesAdvanced Materials Interfaces, EarlyView.
The present work is concerned with the fabrication of CO2 sensors based on MWCNTs/ZnO material, which is obtained by RF magnetron sputtering and electron‐beam deposition methods. The sensor exhibits highly sensitive and selective behavior, high repeatability, and temporal stability at low CO2 concentrations.

Electromechanical Brillouin scattering in integrated optomechanical waveguides [PDF]

open access: yesarXiv, 2019
In the well-known stimulated Brillouin scattering (SBS) process, spontaneous acoustic phonons in materials are stimulated by laser light and scatter the latter into a Stokes sideband. SBS becomes more pronounced in optical fibers and has been harnessed to amplify optical signals and even achieve lasing.
