A numerical procedure based on a two-dimensional finite element formulation is presented to evaluate the induced effects on a multiconductor line excited by an external electromagnetic field. The field incident to the cable is simulated by a plane wave and the line is considered in free space. The coupling problem is described by the homogeneous Helmholtz equation which is solved in the frequency domain. Appropriate open boundary condition techniques are implemented. An accurate investigation is performed to analyze the validity of the Impedance Boundary Conditions (IBC) applied to the conductor surfaces. Some applications are presented to illustrate the validity of the proposed procedure.

Abstract
A numerical procedure based on a two-dimensional finite element formulation is presented to evaluate the induced effects on a multiconductor line excited by an external electromagnetic field. The field incident to the cable is simulated by a plane wave and the line is considered in free space. The coupling problem is described by the homogeneous Helmholtz equation which is solved in the frequency domain. Appropriate open boundary condition techniques are implemented. An accurate investigation is performed to analyze the validity of the Impedance Boundary Conditions (IBC) applied to the conductor surfaces. Some applications are presented to illustrate the validity of the proposed procedure.Pubblicazioni consigliate
