Two-dimensional field computation using boundary integral equations method for stationary and quasistationary problems with external current sources

In the paper, the solutions to electromagnetic field problems in bidimensional systems containing insulating and conducting materials, with forced and induced currents, are examined. To solve these problems, in terms of magnetic vector potential, the boundary integral method is used. The integral formulations of the problems, as well as the discretisation of resulting equations and numerical resolution of equations giving the magnetic potential, are described. Finally, several examples of stationary and quasistationary field calculations are given.
