Open Access research with a real impact on health...

The Strathprints institutional repository is a digital archive of University of Strathclyde's Open Access research outputs. Strathprints provides access to thousands of Open Access research papers by Strathclyde researchers, including by researchers from the Physical Activity for Health Group based within the School of Psychological Sciences & Health. Research here seeks to better understand how and why physical activity improves health, gain a better understanding of the amount, intensity, and type of physical activity needed for health benefits, and evaluate the effect of interventions to promote physical activity.

Abstract

Surface acoustic wave scattering in periodically microstructured surfaces is investigated numerically and experimentally. We perform the simulations by a real-time finite element technique and experiments by ultrashort pulsed optical excitation and interferometric detection. Good agreement is obtained between simulation and experiment. Our results clearly show the opening of phononic stop bands of the excited Rayleigh-like waves at the Brillouin zone boundary. In addition, we investigate the influence of the grating thickness by numerical simulations. Our results show the strong influence of the grating thickness on the position and width of the phononic stop bands.
