dc.description.abstract | This study aims to demonstrate the generation and detection of Scholte waves inside
polystyrene microparticles. This was proven using both experimental analysis and COMSOL simulation. Microspheres of different sizes were excited optically with a pulsed laser (532 nm), and
the acoustic signals were detected using a transducer (40 MHz). On analyzing the laser-generated
ultrasound signals, the results obtained experimentally and from COMSOL are in close agreement
both in the time and frequency domain. A simplified analysis of Scholte wave generation by laser
irradiation for homogeneous, isotropic microspheres is presented. The theoretical wave velocity of
the Scholte wave was calculated and found close to our experimental results. A representation of
pressure wave motion showing the Scholte wave generation is presented at different times. | en_US |
