Abstract

The use of the Finite Element Method in terms of the magnetic vector potential and electric scalar potential has been previously reported. The need for a suitable gauge has been stressed to ensure unique solution, and the Lorentz gauge has been shown to be attractive since it decouples the magnetic vector and electric scalar potentials. The present paper shows how absorbing boundary conditions can easily be included in this method, retaining symmetry in the equations, and thus allowing solutions to problems in which energy radiates away from the solution domain
