| 相关介绍： | Abstract: Computational wave propagation has emerged as a fundamental, vigorously growing technology for modeling, design, and development in areas ranging from seismic imaging, medical imaging, remote sensing, and nanotechnology. I will give an overview of some newly developed fast algorithms for high frequency wave propagation, such as fast sweeping methods for eikonal equations, Gaussian beam methods for the Schrodinger equation based on fast wavepacket transforms, and multiscale Gaussian beam methods for wave equations based on fast multiscale wavepacket transforms. To demonstrate the power of these fast algorithms, I will outline two applications in inverse problems: traveltime tomography and photoacoustic tomography. |
