| Abstract: | 我們將用可穿透聲波來重建非凸集合的障礙物，在二維或者三維的非均勻介質下考慮這個問題。我們需要利用complex geometrical optics solution 來幫助我們重建未知的障礙物。 We develop reconstruction schemes to determine nonconvex penetrable in a region in 2-dimensional or 3-dimensional in an inhomogeneous medium. This algorithm use complex geometrical optics solutions to the equation with general phase in 2-dimension and logarithm phase in 3-dimension. The 2-dimensional case will be demonstrated in section 2 and 3-dimensional case will be demonstrated in 3-dimension. |
