Abstract :
The paper deals with the time-harmonic, electromagnetic analysis of a 3D inhomogeneous radiator/scatterer in free-space, using a finite element-boundary integral (FE-BI) formulation which solves for both the electric and magnetic fields simultaneously. Physics-based, a posteriori error indicators are proposed in this setting.
