Development of ACTEOM node is a part of the DARPA EXTREME program. The node is powered by nanoHUB and provides a versatile in-the-cloud front-end (TOOLKIT) to simulate light propagation in the modern Engineered Optical Materials (EnMats). The project is a result of a close collaboration of fabrication and simulation experts, thus delivering the unique software product with a live connection to the recent research (SHOWCASE) and ability to reproduce optical phenomena in online simulations utilizing original material data (DATABASE, unit-cells) and multi-physics numerical models.
