Abstract
An approximate solution for the acoustic coupling factor (the diffract ion correction function) from a focused transducer to a flat plate and back to the transducer is provided. This function is useful for syste m calibrations where a pulse-echo system or transmit-receive system is used. Numerical solutions are provided for the important case where t he hat plate is placed near the focal plane of the transducer. The sol ution for a hat disk transducer is obtained as a limiting case. Experi mental evidence for a focused transducer is provided.
