RT Journal Article T1 Tuning metamaterials by using amorphous magnetic microwires A1 Lopez-Dominguez, V. A1 Garcia, M. A. A1 Marín Palacios, María Pilar A1 Hernando Grande, Antonio AB In this work, we demonstrate theoretically and experimentally the possibility of tuning the electromagnetic properties of metamaterials with magnetic fields by incorporating amorphous magnetic microwires. The large permeability of these wires at microwave frequencies allows tuning the resonance of the metamaterial by using magnetic fields of the order of tens of Oe. We describe here the physical basis of the interaction between a prototypical magnetic metamaterial with magnetic microwires and electromagnetic waves plus providing detailed calculations and experimental results for the case of an array of Split Ring Resonators with Co-based microwires.
