Voltage and Current Excitation for Time-Harmonic Eddy-Current Problems [PDF]
SIAM Journal on Applied Mathematics, 2008 We give a systematic presentation of voltage or current intensity excitation for time-harmonic eddy-current problems. The key point of our approach resides in a suitable power law that permits us to understand the role of voltage excitation. We also shed light on the influence of the boundary conditions on the proposed formulations.
