B.Matsuda, O.424We present a method based on a combination of temporal and spatial Fourier image analysis, involving the incorporation of a time-reversed acoustic propagation component, that can be used to obtain the angular dispersion or general dispersion relations of multiple surface acoustic modes excited by a localized pulsed source. The method is applied to the study of acoustic propagation at the surface of the highly anisotropic single-crystal TeO2 coated with a thin gold film.American Institute of PhysicsJournal Articleapplication/pdfhttp://hdl.handle.net/2115/5790https://eprints.lib.hokudai.ac.jp/dspace/bitstream/2115/5790/1/APL83-7.pdf0003-6951APPLIED PHYSICS LETTERS837134013422003-08-18enginfo:doi/10.1063/1.1602151Copyright © 2003 American Institute of Physicspublisher
