BUFFALO, N.Y., Sept. 3, 2021 — Research at the University at Buffalo has explored the science behind microscale concave interfaces (MCI) — structures that reflect light to produce beautiful and potentially useful optical phenomena. In a published paper, Buffalo engineering researcher Qiaoqiang Gan defined how light interacts with microscale concave interfaces. Future applications for the technology, he said, could include aiding autonomous vehicles in recognizing traffic signs. The study focused on a retroreflective material — a thin film that consists of polymer microspheres laid down on the sticky side...Read full article
