Keywords

acoustic remote sensing and model-based inversion for applications in acoustic, ultrasonic, seismic and electromagnetic waves. These applications require numerical methods for wave propagation modeling and model-based inversion. The forward models for wave propagation for both range independent and range dependent environment include ray theory, normal modes, wave number integration techniques and the parabolic equation. Common techniques for model-based inversion contain general linear least-squares, singular-value decomposition, regularization, linearization, and global inversion methods such as simulated annealing and genetic algorithms. Applications are drawn from the research literature and include topics such as inversion of geo-acoustics, geo-electromagnetic and seismic data, matched-field inversion, modal decomposition, and remote sensing.

The European Acoustics Association (EAA) is a non-profit entity established in 1992 that includes in its membership societies predominantly in European countries interested in to promote development and progress of acoustics in its different aspects, its technologies and applications. EAA gathers 33 societies of acoustics and serves more than 9000 individual members all over Europe. The European Acoustics Association (EAA) is an Affiliate Member of the International Commission for Acoustics (ICA) and of Initiative of Science in Europe (ISE).
