Broadband and omnidirectional attenuation of bulk waves in transversely isotropic soil by cross-like metamaterials

Runcheng Cai, Yabin Jin, Yan Pennec, Bahram Djafari-Rouhani, Timon Rabczuk, Xiaoying Zhuang

Metamaterials with bandgap properties have been widely studied and applied in the attenuation of surface and bulk waves propagating in the soil. However, most of the studies consider soil as the isotropic medium and ignore the general anisotropy property from the practical point of view. In this…

Electroisomerization blinking of an azobenzene derivative molecule

Sylvie Godey, Hugo Therssen, David Guérin, Thierry Melin, Stéphane Lenfant

Abstract We report here the reversibility and bistability of the switching behavior in an azobenzene derivative induced by the bias applied by a Scanning-Tunneling Microscopy (STM) tip, at low temperature and in ultra-high vacuum environment. This cis-to-trans and trans-to-cis switching were…
