In this thesis, we propose to address the Casimir effect with an hydrodynamic approach based on an acoustical analogy: the acoustic Casimir force. Here, when two plates are immersed in a fluid insonified by ultrasound radiation, a force arises from the acoustic radiation pressure difference between the inner and outer domain delimitated by the plates.
As we have recently shown, this configuration is very promising for manipulating micro particles in a liquid medium by acoustic waves and could be further extended to the case of submicron particles and use of acoustic metamaterials. We also believe this approach could help understanding its electromagnetic counterpart.
