The evolution of modern electromagnetic technologies, such as ultrafast communications, relies on the development of new materials and novel theories. Artificially structured electromagnetic composites, termed metamaterials, offer unique optical properties that do not exist in natural materials, broadening human being's knowledge of manipulating electromagnetic waves. We are particularly intesested in the theory, modeling, and numerical analysis of electromagnetic waves interaction with metamaterials and metasurfaces, metamaterial based antennas and RF devices/systems, active nano antennas, nanophotonics, and surface plasmon polaritons.
