Flexible patches for mm-wave holography

Abstract

In this work, we demonstrate, in simulation and experiment, reflection metasurface holograms operating in the millimeter wavelength range. Flexible holographic metasurface patches are the ideal platform to retrofit existing millimeter wavelength equipment to enhance and extend their functionality, e.g., for antennas and electromagnetic shielding. We present both a rigid and flexible implementation of the holographic metasurfaces, where the meta-atom is based on a three-layered structure with a gold c-ring as the polarization conversion element.
