The approximate analytical solution of the point source problem in 2D heterogeneous media

Autor: Liu Z, Wang X, Zhang S, Benoit Noetinger

The approximate analytical solution of the point source problem in 2D heterogeneous media is provided in this article. It is based on the analytical solution of 2D quasi-Laplace equation, which can be expressed as a combination of piecewise power ser
