Researchers at the University of Pennsylvania have introduced a metamaterial platform capable of solving an arbitrary wave as the input function to an equation associated with a prescribed integral operator. The solution of such an equation is generated as a complex-valued output electromagnetic field. They demonstrated their technique at microwave frequencies through solving a generic integral equation and using a set of waveguides as the input and output to the designed metastructures. The research provides a route to develop chip-based analog optical computers and computing elements…read more. TECHNICAL ARTICLE
