Author Affiliations +
The high frequency permeability of two types of artificial materials are investigated. Composites made of ferromagnetic wires and conductive wires have been manufactured, and their microwave properties have been investigated. Experimental results are reported, and a model is proposed that accounts for the observations. It is underlined that textile technology is very attractive and cost-effective to manufacture metamaterials. The permeability of systems composed of magneto-mechanical oscillators has been investigated theoretically. It is shown that these systems are described by equations similar to that of gyromagnetism. The figure of merits of conventional soft permeable materials and of these magneto mechanical systems are discussed.
