Abstract : Recent developments in computational methods for unbounded electromagnetic problems involving antennas and scattering will be considered. Emphasis will be given to the numerical implementations of differential equation based formulations using either finite differences or finite elements, to be referred to as the finite methods. Elementary examples are used as conceptual vehicles for introducing finite element and unimoment techniques. This is followed by a discussion concerning some of the most recent innovations, such as that of the finite element boundary integral method and the field feedback formulation. Current capabilities are demonstrated by considering some of the most important research results utilizing the finite methods.
