Beamlet and Directional Wavelet: Phase-Space Localization and Wave Propagation Ru-Shan Wu (University of California) SUMMARY____________________________________________________________ First I review the development of beamlet decomposition and propagation in the framework of phase-space localization especially the space-wavenumber localization. Then the relation between the beamlet and the directional wavelet is discussed in the context of wave propagation. Beamlet and directional wavelet have the same capacity of representing phasespace localized wavefield due to the angle-wavenumber correspondence. Some examples of propagator decomposition and seismic imaging using local cosine beamlet propagator are given. EAGE 69 th Conference & Exhibition — London UK 11 - 14 June 2007
