Abstract :
This is a contribution to the magnetic field evaluation of open boundary time-harmonic eddy current problems, using a hybrid finite element/boundary Fourier transform method (FE/BFT). The finite element method applies inside a fictitious cylindrical surface where the conductor lies and the boundary method applies to the whole space outside the cylinder, including a semi-infinite conducting substrate
