A regularization approach for solving Poisson's equation with singular charge sources and diffuse interfaces

Siwen Wang, Arum Lee, Emil Alexov +1

Singular charge sources in terms of Dirac delta functions present a well-known numerical challenge for solving Poisson's equation. For a sharp interface between inhomogeneous media…
