Genetic Algorithms for the Discovery of Homogeneous Catalysts

Rubén Laplaza Solanas, Anne-Clémence Corminboeuf, Puck Elisabeth van Gerwen, Alexandre Alain Schöpfer, Simone Gallarati

In this account, we discuss the use of genetic algorithms in the inverse design process of homogeneous catalysts for chemical transformations. We describe the main components of evolutionary experiments, specifically the nature of the fitness function to o ...

Effect of mechanical nonlinearity on the electromagnetic response of a microwave tunable metamaterial

Romain Christophe Rémy Fleury, Bakhtiyar Orazbayev, Rayehe Karimi Mahabadi, Taha Goudarzi

Tunable metamaterials functionalities change in response to external stimuli. Mechanical deformation is known to be an efficient approach to tune the electromagnetic response of a deformable metamaterial. However, in the case of large mechanical deformatio ...

Fractal-like Mechanical Resonators with a Soft-Clamped Fundamental Mode

Tobias Kippenberg, Alberto Beccari, Nils Johan Engelsen, Sergey Fedorov

Self-similar structures occur naturally and have been employed to engineer exotic physical properties. We show that acoustic modes of a fractal-like system of tensioned strings can display increased mechanical quality factors due to the enhancement of diss ...

Robust wave transport at subwavelength scale with chiral metamaterials

Romain Christophe Rémy Fleury, Bakhtiyar Orazbayev, Nadège Sihame Kaïna

Rapid progress in all types of communication systems imposes each time more strict requirements on the communication devices, requiring having the overall device's size as small as possible, but also increasing the demands on the robustness of the transmis ...

Chiral Metamaterials for a Robust Waveguiding Scheme

Romain Christophe Rémy Fleury, Bakhtiyar Orazbayev, Nadège Sihame Kaïna

Recent advances in the field of metamaterials have shown that waves can be efficiently manipulated at the subwavelength scale through the interactions with an ensemble of resonant inclusions, opening new horizons in overcoming the size limits of devices wh ...

Non-reciprocal manipulation of subwavelength fields in locally-resonant metamaterial crystals

Romain Christophe Rémy Fleury, Farzad Zangeneh Nejad, Nadège Sihame Kaïna

Locally-resonant metamaterial crystals are artificial materials built from small spatially-local resonant inclusions arranged periodically at subwavelength scale. Unlike conventional continuous metamaterials, for which spatial dispersion originates mostly ...

Subwavelength robust waveguiding with chiral metamaterial waveguides

Romain Christophe Rémy Fleury, Bakhtiyar Orazbayev, Nadège Sihame Kaïna

In this work, we design and experimentally demonstrate in the microwave range a robust metamaterial waveguide, which is formed at the boundary between two locally resonant chiral metamaterials with opposite chirality. We show that the interface states at s ...
