Thematic Program on

Wave Propagation in Complex Environments

Duration: 3 months

Academic Year: 2011 – 2012

The subject of the second thematic program is Wave Propagation in Complex Environments and has a duration of three months. In this thematic program we imbed the following three one-week-long workshops:

  • Wave propagation in complex media and applications
    Imaging with waves is widely used in medical imaging, geophysical exploration, ocean acoustics and non–destructive testing of materials, among other applications. The basic idea is to probe a medium with waves (acoustic, seismic or electromagnetic), record the response and infer or image prominent features of the medium (e.g. reflectors, wave velocity) solely from these recordings. This is an emerging interdisciplinary area in applied mathematics, with roots in wave propagation, random media, statistics, optimization and numerical analysis.
    This workshop was focused on forward and inverse wave propagation problems in complex media as they appear in different applications ranging from underwater acoustics and geophysics to more modern meta–materials and nanotechnology.

    The workshop was held in the Foundation for Research and Technology (FORTH) on May 7 – 11, 2012. A dedicated website for the workshop can be found here. The following scientists participated and gave a talk in the workshop:

  • Semiclassical & multiscale aspects of wave propagation
    The purpose of the workshop is to bring together scientists working on stochastic and multiscale aspects of wave propagation and imaging in complex media, with different mathematical tools like microlocal, semiclassical, stochastic analysis and dynamical systems and in different applications from geophysics, nanotechnology and quantum chaos, in order to investigate the role and interconnectivity of their tools in the effective modeling of complex environments either as stochastic media or deterministic media with non–integrable Hamiltonians, and the formulation of scale–adapted imaging setups.

    The workshop was held in the facilities of the center on May 28 – June 1, 2012. A dedicated website for the workshop can be found here. The following scientists participated and gave a talk in the workshop:

  • Waves and imaging in complex media
    Imaging with waves is widely used in medical imaging, geophysical exploration, ocean acoustics and non–destructive testing of materials, among other applications. The basic idea is to probe a medium with waves (acoustic, seismic or electromagnetic), record the response and infer or image prominent features of the medium (e.g. reflectors, wave velocity) solely from these recordings. This is an emerging interdisciplinary area in applied mathematics, with roots in wave propagation, random media, statistics, optimization and numerical analysis.
    This workshop was focused on imaging with waves in complex media with applications in exploration seismology, medical imaging, radar and invisibility cloaks.
