We have made measurements of microwave transmission over the 12 - 18 GHz\nrange and through a simple metamaterial exhibiting a negative index of\nrefraction. The metamaterial consisted of an array of wires cladded in\ndielectric embedded in a magnetic ferrite. The ferrite replaced the cut-ring\nstructure usually used to create the negative permeability. The dielectric\ncladding decoupled the ferrite from the wires, thereby allowing the wire array\npermittivity to be simultaneously negative with the permeability. The\nsimplicity of the design allows for miniaturization of potential microwave\ndevices based on this metamaterial.\n
