Excitation of guided waves in materials with negative refraction
(Elsevier, 2008)
We study, both analytically and numerically, electromagnetic beam transmission through a layered structure that includes a waveguide slab of metamaterial with negative refraction. The resonant excitation of the leaky guided ...
Spatiotemporal instabilities of counterpropagating beams in nematic liquid crystals
(Elsevier, 2008)
We investigate the behavior of counterpropagating self-trapped optical beam structures in nematic liquid crystals. We treat numerically a time-dependent model for the beam propagation and the director reorientation in a ...
