Compact AR Head-Mounted Display Enabled by Multilayered Metasurfaces

The IPP team groups together research activities in the field of the interaction between light and micro and nanostructured media, with the aim of extracting certain information or of modifying the material to give it a specific functionality. The application domains are measurement, instrumentation for healthcare and laser processing.

This project aims to explore and develop a novel full-color metasurface architecture for single waveguide-based HMDswith a wide overall FoV.To achieve full-color functionality, the design will incorporate multilayered metagratings for light propagation within a plastic waveguide.

During the project, the student will evaluate potential design approaches with consideration for fabrication constraints. A model will be developed for selected structures, and the student will design the target configuration using finite-difference time-domain (FDTD) electromagnetic simulations and iterative optimization algorithms. Additionally, a new design tool, powered by a physics-informed generative neural network, will be created to generate multilayered compound metasurfaces capable of multiwavelength operation. The student will thoroughly assess the performance of the designed structures based on the simulation results.
