Cyclic concentrator, carpet cloaks and fisheye lens via transformation plasmonics Alaoui, M. Rustomji, K. Chang, T. M. Tayeb, G. Sabouroux, P. Quidant, R. Enoch, S. Guenneau, S. Abdeddaim, R. Universitat Politècnica de Catalunya. Institut de Ciències Fotòniques Àrees temàtiques de la UPC::Física Optics transformation optics Òptica We first review basic equations of plasmonics in anisotropic media. We recall the origin of Maxwell’s gradient index fisheye lens. We then apply tools of transformation optics to the design of a cyclic concentrator and a variety of plasmonic carpet-cloaks. We further give a brief account of the discovery of spoof plasmon polaritons (SfPPs) by Pendry et al (2004 Science 305 847–8) 150 years after Maxwell invented the fisheye lens. Finally, we experimentally demonstrate a concept of a fisheye lens for SfPPs at microwave frequencies. We stress that perfect metal surfaces perforated with dielectrics offer a playground for moulding surface waves in many areas of physics Peer Reviewed Postprint (published version) 2016-04-01 Article Alaoui, M.
