| Abstract(in English) | Echoes scattered by a step at a bottom surface of a test object and echo dynamic curves are calculated and compared with experimental results. The thickness of the test object is 10 mm, and the height of the step is 0.3 mm (0.5λ). Three types of angle probes are used. The nominal frequency and the transducer size of the probes are 5 MHz and 6×10 mm, respectively, and the refraction angles of the probes are 35°,40° and 45°. The hybrid finite difference method reported previously is used in the calculation. The calculated results are in good agreement with the experimental results. The probe position on the test surface where the maximum echo height is obtained is different from the probe position where the center axis of the beam transmitted from the probe crosses the step. |
