Ferromagnetic wires are proposed to engineer artificial impedance surfaces. The scattering problem of a grid of wires in the proximity of a ground plane is solved, and explicit expressions for the equivalent surface impedance and reflection coefficient are formulated. Due to the wide variety of electromagnetic effects excited by the wires (magneto-impedance effect, magnetic dipolar excitation, and inter-coupling between both effects and higher order effects) ferromagnetic wires provide more design flexibility than state of the art impedance surfaces. The scenario of dominant magnetic dipolar excitation is addressed in detail, demonstrating the possibility of realizing absorbing boundaries as well as capacitive and/or inductive surfaces.
