Title: Imaging resolution by fundamental triple-solution of TPDOT&TWSM

Abstract Imaging for ice structure study, oil reservoir detection, tomography of human body, non-destructive industry control etc. have been based on the simple idea of that the circle-like geometrical Green’s function solves the wave equation. It is correct in some cases. In the general 3D case, however, the full complete set of fundamental solutions consists of a triple: 1) Green’s wave, 2) 1D-diffracted edge wave and 3) 0D-diffracted tip wave. I would like to show you several spectacular examples of models where the use of only Green’s solution gave wrong knowledge about the subsurface. For example, a model with one interface has 9 interfaces on imaging, because only Green’s solution was used and the other two fundamental solutions were neglected. This is a continuation of my first presentation at PICE where I suggested a course on diffraction and showed many diffraction methods. This time I will focus on the proposed method and its results for the past 50 years.
