Dr Jensen Li received his BEng
degree (First Class Honors) in
electrical and electronic engineering from University of Hong Kong and
his PhD degree in physics with Prof C T Chan in Hong Kong University of
Science and Technology in 2004. Before joining City University of Hong
Kong, he worked on metamaterials and invisibility cloak with Prof Sir
John Pendry in Imperial College London, and with Prof Xiang Zhang at
the University of California at Berkeley. His research interests
include metamaterials/plasmonics, photonic crystals, transformation
optics and artifical acoustic materials.
resonance of artificial
atoms is a very flexible building block for engineered optical
materials. These metamaterials give rise to physical properties like a

transformations. Invisibility cloaks, ultra-powerful microscopes and
light concentrators for solar cell applications are only some of the
possibilities in this area.
and ideas in
electromagnetic metamaterials can be extended to acoustics, giving rise
to rich phenomena and novel applications like a negative mass density,
modulus and acoustic sub-diffractional imaging. We need to develop
physical understandings and the feasible ways to construct the
