Nonlinear waves and Acoustics
My research combines theoretical, computational and experimental methods for the study of nonlinear elastic and acoustic waves in materials and metamaterials. I look for a deeper insight into nonlinear wave processes in general, and seek to reveal new wave effects, or peculiar material properties... Applications range from nonlinear wave control by metamaterials (diode effect, absorption, mitigation...), to the characterization of materials by elastic waves and laser-generated ultrasonics.
