Green's Function Method for Solving the Electrostatic Potentialin Anisotropic Dielectric

By use of the Green's function method to solve the Poisson equation in anisotropic dielectric, the electric potential formula of the charged system is obtained, and through the application of the Green function method in solving the two-dimensional Poisson equation, the electric potential of the linear charge is obtained in anisotropic dielectric. And thus the application value of the Poisson equation function with Dirac delta function expression is excavated.
