Real-space Green's function of an isolated point charge in an unbounded anisotropic dielectric.

In modern electronic devices the finite size of the substrates requires three-dimensional analysis. To this end, the boundary element method (BEM) may be utilized. The BEM involves problem-specific Green's functions (GFs), which are to be constructed first. This work has derived a GF which is the electric potential response to an isolated point charge in an unbounded anisotropic dielectric.
