Amit Lal is the Robert M. Scharf 1977 Professor in the School of Electrical and Computer Engineering at Cornell University, Ithaca, NY. He received a B.S. (1990) in Electrical Engineering from Caltech, and a Ph.D. (1996) in Electrical Engineering from the University of California, Berkeley.
GHz ultrasonics on CMOS chips are enabled by integration of fast, deep sub-micron transistors and GHz thin film piezoelectric transducers. Sonic wavelengths on the order of a few microns can generate wave packets with spatial extent that is less than the substrate thickness. Wave packet transport and sensing constitutes a new paradigm for signal processing for precision delays, analog computing, and biological sensing.
