Transformation Optics and the Geometry of Light
Metamaterials are beginning to transform optics and microwave technology thanks to their versatile properties that, in many cases, can be tailored according to practical needs and desires. AlthoughExpand

Fiber-Optical Analog of the Event Horizon
The physics at the event horizon resembles the behavior of waves in moving media. Horizons are formed where the local speed of the medium exceeds the wave velocity. We used ultrashort pulses inExpand

Canonical quantization of macroscopic electromagnetism
Application of the standard canonical quantization rules of quantum field theory to macroscopic electromagnetism has encountered obstacles due to material dispersion and absorption. This has led to aExpand

Observation of Noise Correlated by the Hawking Effect in a Water Tank.
We measured the power spectrum and two-point correlation function for the randomly fluctuating free surface on the downstream side of a stationary flow with a maximum Froude number F_{max}≈0.85Expand

Electromagnetic energy momentum in dispersive media
The standard derivations of electromagnetic energy and momentum in media take Maxwell's equations as the starting point. It is well known that for dispersive media this approach does not directlyExpand

Horizon effects with surface waves on moving water
Surface waves on a stationary flow of water are considered in a linear model that includes the surface tension of the fluid. The resulting gravity-capillary waves experience a rich array of horizonExpand

Optical angular momentum in dispersive media
The angular momentum density and flux of light in a dispersive, rotationally symmetric medium are derived from Noether's theorem. Optical angular momentum in a dispersive medium has no simpleExpand

Observation of negative-frequency waves in a water tank: a classical analogue to the Hawking effect?
The conversion of positive-frequency waves into negative-frequency waves at the event horizon is the mechanism at the heart of the Hawking radiation of black holes. In black-hole analogues, horizonsExpand
