I am grateful to the following Fellows of the Acoustical So-
ciety of America, who taught and inspired me over three
decades: Ed Sullivan. Iirn Candy, and C1ifl' Carter in sonar

underwater acoustics; Tom Howarth and Kim BCDJZEDLD in
an ultrawideband sonar transducers; R, Lee Culver and Whit-
m low An in high-frequency sonar; and Mike Scanlon in battle-
“ field acoustics. In Australia, much was achieved through col-
laborative work programs with Ron Wyber in the research,
