The fabrication of state-of-the-art metasurfaces typically involves several expensive, time-consuming, and potentially hazardous processing steps. Researchers in Sweden have developed a method to construct phase-gradient metasurfaces from an exposed standard electron beam resist. They demonstrated the advantages of the method by constructing high-performance flat optics for the entire visible wavelength range. The method dramatically cuts the required processing time, cost, and reduces safety hazards. The method could be a step towards large-scale production of metasurfaces…read more.
