Hossein Mosallaei Metamaterials Laboratory at Northeastern University enables comprehensive solutions for Maxwell's and Schrodinger's equations, exploits fundamental physics, and creates transformational electromagnetic systems. The goal is to achieve state-of-the-art mathematical models and computational techniques to innovatively solve and characterize novel phenomena in metamaterials platforms. The emphasis is on nanoelectromagnetics, metamaterials and metasurfaces, photonics and plasmonics, hybrid nanomaterials and quantum systems. Our group works from RF to Optics.
