The subsurface, which contains many natural resources (water, gas, oil, etc.), can also constitute a natural risk because of its lithological and topographical characteristics. In the context of climate change, it becomes more and more important to e

Metamaterials are materials designed by man with static or dynamic properties inaccessible to natural materials. Among them, phononic crystals consist of a periodic assembly of two or more materials, and are mainly used for the design of waveguiding

Over the last three decades, seismologists have been successful in probing the Earth's internal structure using copious seismic records gathered at its very surface. Widely known as seismic tomography, one of its central goals is to construct three-d

Imaging the structures in depth of the Pyrenees mountain range is a long-standing subject of study with the aim both of gaining a better understanding of the geodynamic processes responsible for its genesis, and also of enabling us to improve the pre

Seismic anisotropy is often used as a proxy for rock deformation. It arises from the preferred orientation of anisotropic minerals. For instance, olivine in mantellic peridotites align according to mantle flow. However, anisotropy in tomographic mode

Rockfall hazard has to be evaluated and monitored in order to prevent loss of life and infrastructure. In this regard it is important to create event catalogs and understand rockfall dynamics. Seismic waves can help for this purpose as they carry val

My thesis is devoted to novel nano-optical phenomena and devices based on spin-orbit interaction (SOI) of light. First, magnetic spin-locking, i.e., an SOI solely driven by the magnetic field of light, is demonstrated with Bloch surface waves. It pro
