Optical Cloaking and Invisibility

In this research thrust, we investigate various photonic configurations to enable efficient photon harvesting.

– Invisibility on demand:

The scattering potential is judiciously manipulated to eliminate the scatterings from/to particular directions.

– All-dielectric self-cloaked structures:

Objects that are self invisible (i.e. requiring no external cloak) can be constructed purely via dielectric materials.
