A Boundary Element Procedure for 3D Electromagnetic Transmission Problems with Large Conductivity

open access: yesMathematics, 2022
We consider the scattering of time-periodic electromagnetic fields by metallic obstacles, or the eddy current problem. In this interface problem, different sets of Maxwell equations must be solved both in the obstacle and outside it, while the tangential
