Flexible Holographic Metasurface with Surface Topology Dependent Functionality

In a paper published in ACS photonics, we present a flexible holographic metasurface with surface topology dependent functionality.

We demonstrate that the phase contribution of the non-flat metasurface shape determines the symmetry properties of the far field holographic image. Here we also describe a framework to increase the sensitivity of the holographic image to the exact metasurface topology.


This work is of practical relevance for security printing technologies, as well as surface polarization and surface topology sensors.
