Scientists from ITMO’s Faculty of Physics have developed MetaDiT, a generative model for automated design of metasurfaces – superthin optical elements that control light at the nanolevel. The model selects not just the nanostructure’s pattern in an elementary cell but also the key numeric parameters: a metaatom’s thickness, its refraction index, and lattice period – the distance between neighboring elements. With this approach, it’s possible to search for more accurate and versatile designs of flat optics for VR devices, sensors, medical equipment, and photon chips. This project was completed at the joint research center in Qingdao, while the corresponding paper has been accepted to AAAI, one of the leading conferences on AI.
