Scanning acoustic microscope (SAM) has proved to be a powerful new technique for investigation and characterization of mechanical properties of materials, especially, the opaque ones. Non-destructive measurements can be carried out using SAM in the v

The growth of LN single crystals free from defects greatly doped with rare earth elements (RE 3+ ) and having a high optical quality is still an unresolve d problem. Always, crystals of the niobate lithium contain a deficiency in lithium causing the

Using acoustic microscopy at higher frequency, we show the velocity evolutions of surface acoustic waves, in particular Rayleigh waves that depend on porosity for a mesoporous silicon layer. The velocities are obtained from different V (z) curves, wh

This work is dedicated to the simulation study for the transverse and longitudinal mitigation effect on propagation modes in some coated materials (layer/substrate): SiC/Si, Al/SiC. The study is based on the acoustic signal simulation of received by
