Jensen Li is working mainly on photonic crystals and metamaterials. His research revolves around various extraordinary optical phenomena given by metamaterials, with prominent examples such as invisibility cloaking and super-resolution imaging. His current interests are on transformation optics, metasurfaces and complex media. Apart from electromagnetic waves, he is keen on extending the concepts of metamaterials to acoustic waves as well.

Jensen has published 40 research articles including scientific journals and book chapters. He previously received 5 grants as PI from Hong Kong, mainland China and Korea before joining University of Birmingham.


  • PhD in Physics, Hong Kong University of Science and Technology, 2004
  • MPhil in Physics, Hong Kong University of Science and Technology, 2000
  • BEng in Electrical and Electronic Engineering (First Class Honours), 1998


Dr Jensen Li received his BEng degree with first class honours in electrical and electronic engineering from the University of Hong Kong in 1998 and his MPhil, PhD degree in physics from the Hong Kong University of Science and Technology in 2000 and 2004. In this period of time, he worked on the zero-th order photonic band gap and the theoretical proposal of acoustic negative index metamaterials.

From 2005 to 2007, Jensen worked in Imperial College London, with support from a Croucher Foundation postdoctoral fellowship, where he developed a theoretical scheme of carpet cloaking.

From 2007 to 2009, he was a postdoctoral researcher at the University of California at Berkeley, participated in the realization of carpet cloaking at infrared frequencies. He also started to work on acoustic metamaterials with super-resolution there.

From 2009 to 2013, he was an assistant professor at the City University of Hong Kong. He continued his research in metamaterials and also worked on alternative schemes in achieving acoustic negative indices without local resonance from theory to realization.In 2013, he joined University of Birmingham as a senior lecturer.
