Outstanding work of Kim Benjamin on 1–3 composite transducers and acoustic analysis

Kim Benjamin was one of the most productive acoustic system researchers that I have known. Kim, myself, and Walter Boober developed acoustic techniques that increased the productivity of the NUWC acoustic facility by a factor of 10. Kim and I produced a number of patents related to the use of 1–3 composite transducers in naval sonars. The last effort with Kim produced a small diameter, broad band transducer that was tested successfully. Kim was a Fellow of the ASA and is greatly missed.
