摘要
Brillouin light scattering investigations of acoustic vibrations in freestanding membranes, soft-hard bi-layers and patterned wires are described. Studies of longitudinal and transverse standing wave resonances, the wave vector dependence of surface and guided waves as well as their hybridization with flexural and dilational waves are presented. Size effects and the role of reduced dimensions on the acoustic behavior are investigated in soft rectangular polymeric wires on freestanding silicon nitride membranes. The mode frequencies and amplitudes are analyzed in terms of surface Green's functions and the xyz algorithm.
