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…
Morphing for faster computations in transformation optics
Ronald Aznavourian, Sébastien Guenneau
We propose to use morphing algorithms to deduce some approximate wave pictures of scattering by cylindrical invisibility cloaks of various shapes deduced from the exact computation…
