devices and products with affordable cost, providing added value functionalities in a disperse range of materials. Nanophotonic components and devices control and manipulate light by altering its phase, amplitude and polarization states in a desired manner. Wavefront shaping through the control of phase and amplitude has opened a new era of flat optics applications in the areas of integrated optics, holography, flat displays, energy harvesting and mid-infrared photonics. In this instance, artificial media with sub-wavelength thickness, consisting of single (or few) layered alternating materials in the wave propagating direction, namely metasurfaces, enable new functionalities and phenomena, which are not found in nature.
The objective of ALMA project is to develop a flexible technology for adaptable large area functional metasurfaces applications, based on smart (optical) designing, alternative nanofabrication process and post printing technologies. The proposed technology will enable the production of large area optical templates (surfaces), which after a post printing process, will provide tailored functionalities for applications in areas, such as security printing, optical components and energy harvesting systems.
