Properties of Gabor Multipliers for Physical Modeling
Abstract:We present techniques developed for numerical modeling of wave
propagation, and source-signature removal in seismic imaging, based on a
class of linear operators known as Gabor multipliers. These operators are
localized Fourier multipliers, whose action is selectively localized by an
element of a partition of unity. We discuss boundedness and stability
properties for these operators, approximations to PDEs and
pseudodifferential operators, and an approximate functional calculus.
