Excited modes on the materials are responsible for the high contrast obtained in the images. However, conventional lenses suffer from multi-mode excitation. Lamb wave lens proposed earlier overcomes this difBculty. It insonifies material surface at only one incidence angle. In this thesis, material characterization ability of high velocity modes for loaded single layered materials by using Lamb wave lens is investigated. The validity of the theory is checked by comparing simulated and measured V(z) curves obtained from specially prepared sample.54 leavesEnglishinfo:eu-repo/semantics/openAccessAcoustic microscopynon-destructive material characterizationLamb wave lenshigh velocity modesV{z) curvesTA417.23 .Y37 1994Materials--Microscopy.Acoustic microscopy.Thesis
