Temporal control of graphene plasmons
Josh Wilson, Fadil Santosa, Misun Min +1
Electrostatic gating and optical pumping schemes enable efficient time modulation of graphene's free carrier density, or Drude weight. We develop a theory for plasmon propagation i…

Unique determination of the index of refraction from phase-less near-field data in two dimensions
Yat Tin Chow, Fadil Santosa, Gunther Uhlmann
Motivated by non-destructive testing of optical fiber, we consider the problem of determining the index of refraction of a two-dimensional medium from magnitude of the total field…
