Abstract :
A finite element formulation is presented to analyze the EM emission produced by a wire line. The examined two-dimensional domain is discretized by node-based triangular elements where the scalar wave equation in the frequency domain is solved in terms of electric field. The field solution is obtained through an innovative procedure which permits efficient modelling of the physical dimensions of the wire cross sections. The wires are assumed to be located in the vertex nodes of the triangular mesh, and their transversal dimensions are taken into account by modifying adequately the local stiffness and mass matrices of those finite elements where the wires are located. Numerical examples are given and compared with the analytical solutions
