2010 (English)In: Scientific Computing in Electrical Engineering, SCEE 2008 / [ed] Janne Roos and Luis R.J. Costa, Springer Berlin/Heidelberg, 2010, 171-172 p.Conference paper (Other academic)
EM scattering from PEC surfaces are mostly calculated through the induced surface current J. In this paper, we consider PEC surfaces homeomorphic to the sphere, apply Hodge decomposition theorem to a slightly rewritten surface current, and show how this enables us to replace the unknown current with two scalar functions which serve as potentials for the current. Implications of this decomposition are pointed out, and numerical results are demonstrated.
