Penn Engineering Inventors Develop Metastructures for Solving Equations with Waves

U.S. Patent No. 11, 494,461 “Metastructures for solving equations with waves” was awarded and issued on November 8, 2022.  The group of four inventors includes Nader Engheta, PhD, the H. Nedwill Ramsey Professor at Penn Engineering, along with Brian Edwards, PhD, a senior research investigator at Penn Engineering.  The patent describes a metamaterial construct whose physical features cause an optical input signal to be transformed into an output wave that equates to the solution of an integral equation.  This analog method of computing has significant potential advantages of higher computational speed and lower power requirements compared to current digital computing methods.  It may also have applicability in big-data engineering and forecasting applications that involve analysis of physical phenomena described by integral equations.  This patented work builds upon Dr. Engheta’s larger body of work on novel materials that interact with electromagnetic waves in unique ways, for which he received the Benjamin Franklin Medal in Electrical Engineering in 2023.
