  • A class of exactly solvable models for the Schrodinger equation 

    Downing, C.A. (Springer Verlag, 2013-10-23)

  • A class of invisible inhomogeneous media and the control of electromagnetic waves 

    Vial, B; Liu, Y; Horsley, SAR; Philbin, TG; Hao, Y (American Physical Society, 2016)
    We propose a general method to arbitrarily manipulate an electromagnetic wave propagating in a two-dimensional medium, without introducing any scattering. This leads to a whole class of isotropic spatially varying permittivity ...
