Invisibility carpet in a channel with a structured fluid
Guillaume Dupont, Sebastien Guenneau, Stefan Enoch
We first note it is possible to construct two linear operators defined on two different domains, yet sharing the same spectrum using a geometric transform. However, one of these tw…
Numerical Analysis of Three-dimensional Acoustic Cloaks and Carpets
Guillaume Dupont, Mohamed Farhat, Andre Diatta +2
We start by a review of the chronology of mathematical results on the Dirichlet-to-Neumann map which paved the way towards the physics of transformational acoustics. We then rederi…
Plasmonic interaction of light with negative index and gold nano-checkerboards
Sangeeta Chakrabarti, S. Anantha Ramakrishna, Neeraj Shukla +4
Negative refractive index materials (NRIM) make possible unique effects such as a convergent at lens due to the reversed Snell-Descartes laws of refraction. NRIM are also known to…
Curved trajectories on transformed metal surfaces: Luneburg lens, beam-splitter, invisibility carpet and black hole for surface plasmon polaritons
Kadic Muamer, Dupont Guillaume, Tieh-Ming Chang +2
Transformational optics are shown to markedly enhance the control of the electromagnetic wave trajectories within metamaterials with unconventional functionalities such as a beam s…
Invisible waveguides on metal plates for plasmonic analogues of electromagnetic wormholes
Muamer Kadic, Guillaume Dupont, Sebastien Guenneau +1
We introduce two types of toroidal metamaterials which are invisible to surface plasmon polaritons (SPPs) propagating on a metal surface. The former is a toroidal handlebody bridgi…
