Most of us will have at some time thrown a pebble into water, and watched the ripples spread outwards and fade away. But now there is also a way to reverse the process, and make those ripples turn around and reconverge again, …and again, and again. To do this we have designed the Maxwell's fishpond, a water wave or ‘transformation aquatics’ version of the Maxwell's fisheye lens (Tyc et al 2011 New J. Phys. 13 115004; Luneburg 1964 Mathematical Theory of Optics). These are transformation devices… 
Cloaks, editors, and bubbles: applications of spacetime transformation theory
Spacetime or ‘event’ cloaking was recently introduced as a concept, and the theoretical design for such a cloak was presented for illumination by electromagnetic waves [McCall et al., J. Opt. 2011].
On spacetime transformation optics: temporal and spatial dispersion
The electromagnetic implementation of cloaking, the hiding of objects from sight by diverting and reassembling illuminating electromagnetic fields has now been with us ten years, while the notion of

Maxwell fisheye lens as a waveguide crossing for integrated photonics
We demonstrate that the Maxwell fisheye lens realized can serve as an ideal waveguide crossing hub for up to 8 waveguides with 0.1 dB loss (97.7% transmission) and crosstalk of -40 dB.
Contrôle des ondes de flexion dans les plaques
Le controle de la propagation des ondes electromagnetiques et acoustiques s’est largement developpe ces dernieres annees par l’utilisation de milieux complexes tels que les cristaux photoniques ou
Is the Maxwell–Shafer fish eye lens able to form super-resolved images?
The imaging capabilities of a modification of the Maxwell fish eye lens proposed by Shafer in the early 1990s are studied theoretically. A wave propagator for this system is derived for a


Horizon effects for surface waves in wave channels and circular jumps
Surface waves in classical fluids experience a rich array of black/white hole horizon effects. The dispersion relation depends on the characteristics of the fluid (in our case, water and silicon oil)
Perfect imaging without refraction?
Recent work suggesting that ‘perfect’ far-field imaging is possible using Maxwell's fish-eye lens (Leonhardt 2009 New J. Phys. 11 093040) has raised a number of questions and controversies about the
Plasmonic Luneburg and Eaton lenses.
Transformation optics provides an alternative approach to controlling the propagation of light by spatially varying the optical properties of a material and grey-scale lithography is used to adiabatically tailor the topology of a dielectric layer adjacent to a metal surface to demonstrate a plasmonic Luneburg lens that can focus surface plAsmon polaritons.
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, horizons

Shallow water analogue of the standing accretion shock instability: experimental demonstration and a two-dimensional model.
The first laboratory experiment of a shallow water analogue, based on the physics of hydraulic jumps, is reported, which demonstrates a robust linear instability and nonlinear properties of symmetry breaking in a system which is one million times smaller and about one hundred times slower than its astrophysical analogue.
Transformation optics and metamaterials
We review recent progress in developing a new class of specially designed optical metamaterial spaces with functionalities that cannot be obtained with conventional optics or natural materials. These
Maxwell fisheye and Eaton lenses emulated by microdroplets
It is demonstrated that microlenses may act as a two dimensional fisheye or an inverted Eaton lens and an asymmetric Eaton lens may exhibit considerable image magnification.
Multi-focal spherical media and geodesic lenses in geometrical optics
This paper presents a general approach to designing isotropic spherical media with complex spatial structure that provide different types of imaging for different light rays. It is based on
