    A general procedure to design objects that are intrinsically invisible (without the necessity of an external cloak) has not been demonstrated so far. Here we propose a flexible method to design such self-cloaked objects ...
  • Ahmed, Waqas Waseem; Herrero, Ramon; Botey, Muriel M.; Hayran, Zeki; Kurt, Hamza; Staliünas, Kestutis (American Physical Society, 2018-03-15)
    We propose an approach based on a local Hilbert transform to design non-Hermitian potentials generating arbitrary vector fields of directionality, p→(r→), with desired shapes and topologies. We derive a local Hilbert ...
  • Oner, B.B.;  Can, M.G.;  Kurt, Hamza (Optical Society Of American (OSA), 2014-08)
    We propose broadband one-dimensional optical cloaking design based on isotropic and purely dielectric non-absorbent materials. The photonic structures are formed by utilizing graded index (GRIN) concept in stacked form. ...
