| Popis: | Funding: This work was supported by DSTL (DASA grant ACC6004053). J.B. and A.D.F. acknowledge support from EPSRC (Grant Nos. EP/M508214/1 and EP/L017008/1). A.D.F is supported by the European Research Council (ERC) under the European Union Horizon 2020 research and innovation programme (grant agreement No. 819346). 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 extendtheir 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.
