Measurement of mechanical characteristics of materials using the X-Z mode of a Scanning acoustic microscope (230 MHz) was conducted on polymer and other materials. These results were compared with those derived using a conventional ultrasonic probe. For the case in which a SAM was used, SAM was used to determine the velocities of the longitudinal wave in Polymer and surface acoustic wave in metals and ceramics. Theoretical analysis of wave propagation was carried out considering the weight density and an acoustic velocity of water.
