Flat lensing by periodic loss-modulated materials
Pradeep Kumar, Nikhil; Herrero Simon, Ramon; Botey Cumella, Muriel; Staliunas, Kestutis (2013-09-23)
Article
Accés obertWe propose a flat lensing effect using a periodic loss-modulated material. In particular, we consider a two-dimensional square and rhombic arrangement of lossy cylinders embedded in a host media with the same refractive ... -
Managing spatial diffraction through a periodic loss modulation
Botey Cumella, Muriel; Pradeep Kumar, Nikhil; Herrero Simon, Ramon; Maigyte, Lina; Staliunas, Kestutis (2014)
Comunicació de congrés
Accés obertWe show that periodic distributions of gain or losses on the wavelength scale allow managing spatial diffraction of light beams, with no index contrast. It has been recently predicted that such artificial periodic structures, ... -
