Acoustic cloaking and mirages with flying carpets
Andre Diatta, Guillaume Dupont, Sebastien Guenneau +1
Carpets under consideration here, in the context of pressure acoustic waves propagating in a compressible fluid, do not touch the ground: they levitate in mid-air (or float in mid-…
Focusing: coming to the point in metamaterials
Sebastien Guenneau, Andre Diatta, Ross McPhedran
The point of the paper is to show some limitations of geometrical optics in the analysis of subwavelength focusing. We analyze the resolution of the image of a line source radiatin…
Tessellated and stellated invisibility
Andre Diatta, Andre Nicolet, Sebastien Guenneau +1
We derive the expression for the anisotropic heterogeneous matrices of permittivity and permeability associated with two-dimensional polygonal and star shaped cloaks. We numericall…
Revolution analysis of three-dimensional arbitrary cloaks
Guillaume Dupont, Sébastien Guenneau, Stefan Enoch +4
We extend the design of radially symmetric three-dimensional invisibility cloaks through transformation optics to cloaks with a surface of revolution. We derive the expression of t…
