PROFESSOR JIPING HUANG

When J. K. Rowling described Harry Potter's invisibility cloak as "fluid and silvery", she probably wasn't thinking specifically about silver-plated nanoparticles suspended in water. But a team of theorists believe that using such a set-up would make the first soft, tunable metamaterial — the "active ingredient" in an invisibility device.
 
The fluid proposed by Ji-Ping Huang of Fudan University in Shanghai, China, and colleagues, contains magnetite balls 10 nanometers in diameter, coated with a 5-nanometer-thick layer of silver, possibly with polymer chains attached to keep them from clumping.
  Jiping Huang, Ph.D. is Department of Physics, Fudan University, Shanghai, China. His research field is soft matter and interdisciplinary physics.
 
Jiping coauthored New Nonlinear Optical Materials: Theoretical Research, Enhanced nonlinear optical responses of materials: Composite effects, Effective nonlinear optical properties of graded metal—dielectric composite films of anisotropic particles, Electrorotation in graded colloidal suspensions, Optical nonlinearity enhancement of graded metallic films, Dielectric response of graded spherical particles of anisotropic materials, Electrorotation of a pair of spherical particles, Second-harmonic generation in graded metallic films, and Nonlinear ac response of anisotropic composites.
 
Jiping earned his BSc in 1998 from Suzhou University, his MSc in 2000 from Suzhou University and his Ph.D. in 2003 from the Chinese University of Hong Kong. He was a Postdoc and Research Fellow at the Max-Planck Institute for Polymer Research in Germany from 2003 to 2005.
