Description

Recent modelling studies [1], [2] have shown that it is possible to develop simple analytical expressions for the scattering of flat-bottom holes and spheres that can be used for quantitative ultrasonic calibration measurements. In the flat-bottom hole case these models have been tested experimentally, yielding excellent agreement even well into the near-field region of the transducer [3].
