Following the 2013 proposal by Tania Puvirajesinghe (CRCM, Institut Paoli-Calmettes, Aix-Marseille University) of a biocloak for the control of drug release (in collaboration with Sebastien Guenneau at Institut Fresnel), some experiments have shown that surrounding graphene sheets by layers of amino-acids makes a biocloak that not only kills tumoral cells (in vitro experiments for internalization of a nanoparticle into a breast cancer cell for further drug release, as shown in the below (...)

Water wave cloaking Researchers at Institut Fresnel have designed and experimentally tested in collaboration with the group of Bernard Molin at IRPHE the first large scale water wave invisibility carpet in a 17m meter long water wave channel (see upper figure, with the photo of the metamaterial carpet and numerical simulations illustrating the reduced disturbance of reflected wavefronts in the channel thanks to the carpet). Researchers at IF have also tested a cylindrical invisibility (...)

Electromagnetic metamaterials, which are composite structures displaying highly dispersive properties enabling artificial magnetism, have been introduced by John Pendry at the turn of the 21st century, in collaboration with his colleagues in London and Duke Universities.
At the same period, the group of Ping Sheng in Hong-Kong has introduced the concept of acoustic metamaterials, which are also locally resonant structures displaying strong frequency dispersion enabling negative effective (...)

A famous example of microwave metamaterials are split ring resonators and swiss rolls which have been introduced by Sir John Pendry in 1999 for artificial magnetism and chirality.
However, the group of Daniel Maystre at the laboratoire d’optique electromagnetique, one historical component of Institut Fresnel, has conducted theoretical and numerical studies of low frequency plasmons in dilute arrays of highly conducting fibers back in the mid-90’s, a subject also popularized by Pendry’s (...)
