On the feasibility of using ferromagnetic materials for thin EM absorbers

Abstract
In this paper the magnetization of a ferro-or ferri-magnetic material has been modeled with the Landau-Lifshitz-Gilbert (LLG) equation. We show that with the aid of a static magnetic bias field the material can be switched between a Lorentz-like material with a resonance frequency and a material exhibiting a magnetic conductivity. The reflection from a magnetic material backed by a perfect electrical conductor (PEC) is then analyzed. It is found that one can achieve low reflection (around -20 dB) for a quite large bandwidth (more than two decades).
