2014 Vannevar Bush Fellow Creates Metamaterials for Solving Integral Equations at Unprecedented Speeds

Dr. Nader Engheta uses complicated composites called metamaterials to make computers that operate with light, rather than electricity. Boundary conditions are set by the A metamaterial device that can solve integral equations.

"With microwaves, our analysis has shown that a solution can be obtained in hundreds of nanoseconds, and once we take it to optics, the speed would be in picoseconds." 

The research was supported by the Basic Research Office of the Assistant Secretary of Defense for Research and Engineering through its Vannevar Bush Faculty Fellowship program and by the Office of Naval Research through Grant N00014-16-1-2029.
