Achievement Award of the IEEE Sonics and Ultrasonics Group

Summary form only given, as follows. John De Klerk (SM´57-F´75) is the first recipient of the IEEE Sonics and Ultrasonics Group Achievement Award. The award, which will be presented in November at the 1980 Ultrasonics Symposium in Boston, MA, USA is intended to acknowledge outstanding contributions in the field of sonics and ultrasonics and to the SU Group. John de Klerk was responsible for a number of major developments in surface acoustic wave (SAW) devices and microwave acoustics. He designed the first SAW device which encoded and decoded a 13-bit Barker phase code whichis now in use in nearly all three-dimensional ground radar systems. He holds four US patents in the field of ZnO thin fdm transducers-work which has led to the development of bulk mode delay lines and resonators - and has contributedt o the fundamental knowledge of bulk mode propagation phenomena. In 1978 he was the recipient of a special patent award by the Westinghouse Electric Corporation. He is currently a Consulting Scientist at the Westinghouse Research and Development Center, Pittsburgh, PA, having served previously as Manager of the Praetersonics Department. He has served as Editor of the Ultrasonics Symposium hceedings and has been Vice President and President of the Sonics and Ultrasonics Group.
