Tomography, Adjoint Methods, Time-Reversal, and Banana-Doughnut Kernels (2004, methodology): “In the case of the SHS β kernel, the broad, low-sensitivity red zone represents the first Fresnel zone, whereas the sidelobes defined by the narrow, high-sensitivity green zone correspond to the second Fresnel zone (e.g. Hung et al. 2000).”
Seismic imaging: From classical to adjoint tomography (2012, background): “…by mode coupling (e.g., Li and Romanowicz, 1995; Li and Tanimoto, 1993; Marquering et al., 1998), body-wave ray theory (e.g., Dahlen et al., 2000; Hung et al., 2000), surface-wave ray theory (e.g., Zhou, 2009; Zhou et al., 2004, 2005), normal-mode summation (e.g., Capdeville, 2005; Zhao and…”
Wavefront healing: a banana–doughnut perspective (2001, background): “The original papers describing the theory (Dahlen et al. 2000; Hung et al. 2000) will henceforth be referred to as Banana–Doughnut I and II.”
AxiSEM: broadband 3-D seismic wavefields in axisymmetric media (2014, background): “The kernel exhibits considerable heterogeneity (partly due to saturated colorscales to highlight its complexity), notably missing the “donut-hole” that is present for pure P wave kernels (Hung et al., 2000).”
Determination of the influence zone for surface wave paths (2002, unknown): “D sensitivity kernels (Marquering et al. 1998, 1999; Dahlen et al. 2000; Hung et al. 2000; Zhao et al. 2000).”
Forward and adjoint simulations of seismic wave propagation on fully unstructured hexahedral meshes (2011, background): “The variation in traveltime δT may be written to first order in terms of perturbations in pressure as δ p (Hung et al. 2000) δT = 1 N ∫ ∂t p δp dt, (A13) where N = ∫ p ∂2t p dt .”
Imaging seismic velocity structure beneath the Iceland hot spot: A finite frequency approach (2004, background): “D) structure off the geometric ray path [Dahlen et al., 2000; Hung et al., 2000; Zhao et al., 2000].”
Frechet Kernels for Imaging Regional Earth Structure Based on Three-Dimensional Reference Models (2005, unknown): “The phase-delay kernels also exhibit typical banana-doughnut shape (Dahlen et al., 2000; Hung et al., 2000; Zhao et al., 2000) with diminishing amplitude along the ray paths.”
Multiscale seismic tomography (2001, background): “However, it does not seem to be physically justifiable to choose a particular width of the weighting function w(r), unless the formulation is based on other finite theory (e.g. Marquering et al. 1999; Hung et al. 2000) rather than the ray theory.”
Three‐dimensional sensitivity kernels for surface wave observables (2004, background): “…properties of seismic body waves (Yomogida 1992; Marquering et al. 1998; Friederich 1999; Marquering et al. 1999; Dahlen et al. 2000; Hung et al. 2000; Dalkolmo & Friederich 2000; Zhao et al. 2000; Kárason & van der Hilst 2001; Montelli et al. 2003); surface waves (Snieder 1986;…”
