A team of researchers at Penn State have devised a new, streamlined approach to designing metasurfaces, a class of engineered materials that can manipulate light and other forms of electromagnetic radiation with just their structures. This rapid optimization process could help manufacture advanced optical systems like camera lenses, virtual reality headsets, holographic imagers and more, the team said.
The method, which was featured on the cover of the October issue of Nanophotonics, uses large language models (LLMs) to accurately predict how a metasurface will influence light. LLMs are a type of artificial intelligence (AI) model capable of learning and improving an action over time based on provided training data and repeated behavior. This approach bypasses the traditional metasurface simulation process that required extensive domain knowledge and time, making it possible for engineers to quickly design these nanoscopic materials and predict how they will influence light solely through prompts fed to AI.
