Dave McIlroy and his co-PI, John O'Hara (ECE-CEAT), have a new grant for $540k for three years from the Air Force Office of Scientific Research. The project title is, "Metamaterials for Nonlinear Coupling and Decoupling of Opto-Electronics and -Mechanical Systems." The project has two components. The first is to develop metamaterials that enhance non-linear coupling in the THz band of the electromagnetic spectrum. The second component is to develop ways to decouple surface plasmon polaritons, as well as explore ways to redirect photon momentum, in solar sails. While the two projects seem miles apart, they involve similar materials and are complementary to one another.
