Bruce Thompson: Adventures and advances in ultrasonic backscatter

“…John Mittleman's Ph. D. thesis work dealt with the effect of precipitates at grain boundaries on backscatter [51,52]. He computed scattering amplitudes for model grains having an inner core of one material and an outer shell of another.…”
