Recently, exciting new physics of metamaterials has inspired a series of key explorations to manipulate, store and control the flow of information and energy at unprecedented dimensions. In the optical domain, we report our development of quantitative near field optical probes to measure the distinct local modes in the nanostructures that promote electron-photon interaction down to layers of a few atoms thick, which promise to strong Purcell effects that are of interest to efficient light emission and detection. These novel metamaterials could be the foundation of broadband photo-absorbers, directional emitters, as well as compact and power-efficient devices.
The remarkable success of electromagnetic metamaterials stimulated exploration of controlling and manipulation of other form of waves in materials. In the arena of sound waves, we demonstrated focusing and rerouting ultrasound through broadband and highly transparent metamaterials. Recently our research effort on acoustic metamaterials has been expanded to tailoring the wavefront and energy flow of elastic waves.
Nicholas X. Fang received his BS and MS in physics from Nanjing University, and his PhD in mechanical engineering from University of California Los Angeles. He arrived at MIT in Jan 2011 as d'Aberloff Career Development Associate Professor of Mechanical Engineering. Prior to MIT, he worked as an assistant professor at the University of Illinois Urbana-Champaign. Professor Fang's areas of research look at nanophotonics and nanofabrication. His recognitions include the ASME Chao and Trigger Young Manufacturing Engineer Award (2013); the ICO prize from the International Commission of Optics (2011); an invited participant of the Frontiers of Engineering Conference by National Academies in 2010; the NSF CAREER Award (2009) and MIT Technology Review Magazine's 35 Young Innovators Award (2008).
