Fabricated cylindrical cloaking shell.

Simulation of fields interacting with an ideal cloaking shell.

My group has been involved in research on how the coordinate transformation invariance of certain wave equations can be exploited to produce specifications for novel materials and devices, such as electromagnetic cloaking shells. Key results we've produced include the first full wave simulations of these materials which demonstrated their experimental feasibility, and the theoretical extension of these concepts to acoustics, in which we showed that acoustic cloaking shells and other devices are also possible.
