Numerical Computation of Electromagnetic Fields

Computational electromagnetics has become an important field both for academic research and for the engineering design of electrical devices. It is an involved region of applied mathematics where advanced mathematical methods are applied to paritcular questions of electrical engineering. In this talk, some basic computational methods for time harmonic fields in scattering problems are discussed. The emphasis will be on wave function series and integral representations of the fields which, alone with the finite element and difference methods, still play an important role in the practical field computation.
