Electromagnetic cloak design with mono-objective and bi-objective optimizers: seeking the best tradeoff between protection and invisibility
Ronald Aznavourian, Guillaume Demesy, Sébastien Guenneau +1
We revisit the design of cloaks, without resorting to any geometric transform. Cancellation techniques and anomalous resonances have been applied for this purpose. Instead of a ded…

Bio-inspired seismic metamaterials: Time domain simulations in transformed crystals
Ronald Aznavourian, Tania Puvirajesinghe, Stephane Brule +2
We introduce the concept of transformation crystallography which consists of the application of geometric transforms to periodic structures. We consider motifs with three-fold, fou…
