Exact and Approximate Expansions with Pure Gaussian Wave Packets
j,k and aligned at an angle of 2⇡k 2j radians. Like other parabolic systems, such as curvelets and shearlets, these wavepackets are particularly useful in geophysics (see for example [7]). In this paper, we consider expansions and approximate expansions of L2(R2) functions in terms of these packets using Gaussian windows. As with Morlet’s wavelets, one can circumvent the problem of the lack of ...
متن کاملExact results for ‘ bouncing ’ Gaussian wave packets
We consider time-dependent Gaussian wave packet solutions of the Schrödinger equation (with arbitrary initial central position, x0, and momentum, p0, for an otherwise free-particle, but with an infinite wall at x = 0, so-called bouncing wave packets. We show how difference or mirror solutions of the form ψ(x, t)−ψ(−x, t) can, in this case, be normalized exactly, allowing for the evaluation of a...
متن کاملElastic Gaussian Wave Packets in Isotropic Media
The theory of Gaussian wave packet (GWP) propagation in elastic materials is developed. The GWP solutions are in the form of localized disturbances with Gaussian spatial envelopes at any instant in time. The method is explicitly time dependent, but is conceptually no more difficult than time halmonic ray theory. The equations of propagation and evolution are very similar to those of standard, e...
متن کاملGeometric Segmentation Using Gaussian Wave Packets
We segment seismic data based on the geometric information provided by sparse gaussian wave packet representations. We use this information to for estimates an abundance of candidate curves for the identification of the wave fronts. A graph cut methodology is then employed to reduce the number of curves such that the data is well described by only few wave fronts.
متن کاملOn the Representation of Functions with Gaussian Wave Packets
1. Introduction. The main purpose of this paper is to develop algorithms to obtain sparse representations of functions of several variables using Gaussian wave packets. Numerically, we will primarily focus on the two-dimensional case; our main interest is the representation of waves related to the wave equation. Sparse representations are useful, in some cases essential, for large-scale problem...
