How to calculation the potential distribution for a dielectric cylinder placed in electric field of point charge?
The height of the dielectric cylinder is H, while its section radius is R. The dielectric constant of the cylinder is ε1.

I found that it is hard for me to write its Laplace Equation and the boundary conditions.
Maybe, a cylindrical coordinate system should be used in the analysis.
Could anyone give me some help?
Thanks very much!
p.s. I wrote a half-baked Laplace Equation for the system in the following URL.
