John Page

"I feel very thrilled and honoured to be the recipient of the 2015 Brockhouse Medal. This recognition by the Canadian Condensed Matter and Material Physics community is a wonderful tribute that also reflects the contributions of my talented graduate students, postdoctoral fellows and collaborators with whom I have had the pleasure of working." winner citation

The Canadian Association of Physicists (CAP) is pleased to announce that the 2015 CAP/DCMMP Brockhouse Medal is awarded to John Page, University of Manitoba, in recognition of for significant and original contributions to the understanding of ultrasonic wave phenomena in complex media through the development and application of new experimental techniques to characterize the structure and dynamics of such materials, including the first demonstration of Anderson localization of classical waves by disorder in three dimensions. announcement

John Page leads the internationally recognized Ultrasonics Research Laboratory in the Department of Physics and Astronomy at the University of Manitoba, where he holds the title of Distinguished Professor. He came to the University of Manitoba in 1985 as an NSERC University Research Fellow, following doctoral studies at the University of Oxford as a Rhodes Scholar and postdoctoral positions at Université Paris VI and Queen’s University. Described as “Canada’s leading expert in fundamental acoustics”, he specializes in the study of novel wave phenomena in strongly scattering condensed matter systems and in the development of new ultrasonic scattering techniques to probe the structure and dynamics of heterogeneous materials.

Backed by strong support from NSERC, Dr. Page has made outstanding contributions to understanding the wave physics of disordered mesoscopic materials, culminating in his recent work on the Anderson localization of ultrasound - the first unambiguous demonstration of this remarkable effect in three dimensions. Classical wave localization has been the most challenging and fascinating aspect of wave transport in disordered media for over 25 years; the impact of Page’s work on localization is already very significant, influencing experimental methods now being used in optics and enabling aspects of Anderson localization to be investigated that have not been seen before.

His pioneering research on phononic crystals has opened new directions in this field, and has been widely acclaimed both nationally and internationally. His most recent accomplishment in this domain is the first demonstration of super-resolution focusing of ultrasound by negative refraction in a flat phononic crystal lens.

By inventing techniques in field fluctuation spectroscopy, he has developed powerful methods for monitoring the evolution of time-varying materials. His research is impacting other areas of science, from optics to seismology, and underpins his strong interdisciplinary collaboration investigating the physical properties of foods and other industrially relevant biomaterials. nominator citation
