3:45pm –5:15pm
Room 31, Tampa Convention Center

Prof. Chris R. Fuller finished his B.E.(Hons) and Ph.D. at Adelaide University, Australia in 1974 and 1978 respectively. His Ph.D. topic concerned re-active attenuation of sound in ducts. He then spent three years at the ISVR, University of Southampton as a Research Fellow studying coupled vibrations in fluid-filled cylinders. After this, Prof. Fuller moved to the U.S. where he worked at NASA Langley Research Center as an NRC Research Associate for two years studying control of aircraft inlet and interior noise. In 1983 he accepted a faculty position at Virginia Tech where he is now the Samuel Langley Distinguished Professor of Engineering and is based primarily at the National Institute of Aerospace in Hampton, VA. Prof. Fuller's current research interests are in acoustics meta materials, active control of sound and vibration, noise in aerospace systems and noise in medical systems. Prof. Fuller has authored over one hundred and seventy papers in various major technical journals and holds over ten patents in active control. He is a Fellow of the Acoustical Society of America and an Associate Fellow of the AIAA. Prof. Fuller has served on the Board of Directors of the International Institute of Sound and Vibration and the Institute of Noise Control Engineers. He is the lead author of the text Active Control of Vibration published by Academic Press. Prof. Fuller has taught over a dozen short courses in active noise and vibration control in the US, Japan, Europe and Australia.

Presentation Title: Acoustic Meta Materials

Acoustic meta materials(AMM) are commonly defined as “materials that have properties not readily available in nature”. As such AMM show high potential for developing new classes of passive acoustic materials with improved, designable properties such as absorption, transmission loss and diffraction. The designable nature of AMM makes them particularly attractive for use for noise control in industry. To this date work in AMM has focused on research and there is very little development of products, mainly due to scalability and difficulties in bulk manufacturing. In this presentation the concepts and early work in AMM will be reviewed. The analytical developments and application of Transformational Acoustics to designing AMM will be briefly described. Recent work in developing poro-elastic AMM which have potential to be productized will be discussed as well as the use of Transformational Acoustics in designing absorbing materials with solid material matrices. Some new, promising directions in AMM will be briefly outlined.
