[HTML][HTML] Neural network based design of metagratings
S Inampudi, H Mosallaei - Applied Physics Letters, 2018 - pubs.aip.org
Metagratings are flat and thin surfaces that rely on unique, periodically repeating (non-
gradient), arbitrary shaped light scattering units for wave manipulation. However, the
absence of an empirical relationship between the structural and diffraction properties of the
units enforces utilization of brute force numerical optimization techniques to determine the
unit shape for a desired application. Here, we present an artificial neural network based
methodology to develop a fast-paced numerical relationship between the two. We …
