Tunable metasurfaces for dynamical control of the properties of radiation (Conference Presentation)

Research in nanophotonic materials and design is yielding advances that are opening conceptually new paths to the realization of metasurfaces consisting of tunable nanoantenna arrays. These tunable metasurfaces can enable dynamic, active control of all of the key constitutive properties of light – amplitude, phase, wavevector and polarization – opening new applications such as phased-array optical beam steering, reconfigurable flat optics, visible light modulation for communication and thermal radiation management.
