A phase-field approach to shape and topology optimization of acoustic waves in dissipative media

Harald Garcke, Sourav Mitra, Vanja Nikolić

We investigate the problem of finding the optimal shape and topology of a system of acoustic lenses in a dissipative medium. The sound propagation is governed by a general semiline…

Isogeometric shape optimization for nonlinear ultrasound focusing

Markus Muhr, Vanja Nikolić, Barbara Wohlmuth +1

The goal of this work is to improve focusing of high-intensity ultrasound by modifying the geometry of acoustic lenses through shape optimization. The shape optimization problem is…
