Estimates for the electric field in the presence of adjacent perfectly conducting spheres
Habib Ammari, George Dassios, Hyeonbae Kang, Mikyoung Lim · Quarterly of Applied Mathematics · 2007
In this paper we prove that, unlike the two-dimensional case, the electric field in the presence of closely adjacent spherical perfect conductors does not blow up even though the separation distance between the conducting inclusions approaches zero.
