Anomalous diffraction in hyperbolic materials
Alessandro Alberucci, Chandroth Pannian Jisha, Allan D. Boardman +1
We demonstrate that light is subject to anomalous (i.e., negative) diffraction when propagating in the presence of hyperbolic dispersion. We show that light propagation in hyperbol…
Dirac-Point Solitons in Nonlinear Optical Lattices
Kang Xie, Qian Li, Allan D. Boardman +10
The discovery of a new type of solitons occuring in periodic systems without photonic bandgaps is reported. Solitons are nonlinear self-trapped wave packets. They have been extensi…
Strong gyrotopy in a chiral toroidal medium
N. Papasimakis, V. A. Fedotov, K. Marinov +2
In this letter, we present the first experimental study of a new chiral metamaterial consisting of toroidal wire windings. We show that the metamaterial exhibits three bands of cir…
Toroidal metamaterial
K. Marinov, A. D. Boardman, V. A. Fedotov +1
It is shown that a new type of metamaterial, a 3D-array of toroidal solenoids, displays a significant toroidal response that can be readily measured. This is in sharp contrast to m…
Radiation enhancement and radiation suppression by a left-handed metamaterial
A. D. Boardman, K. Marinov
The perfect lens property of a dispersive and lossy left-handed metamaterial (LHM) disk is exploited to superimpose a source of electromagnetic radiation onto its mirror image, for…
Dissipative magneto-optic solitons
Allan D. Boardman, Larry Velasco, Peter Egan
Magneto-optic behaviour is a specific, non-reciprocal example of gyrotropic behaviour. When coupled to photo-induced Faraday rotation it is possible to discriminate this effect fro…
