Metamaterial constructed by a Cu-wire coil wound on a ferrite core exhibits greatly enhanced imaginary permeability μmax″, large negative real permeability μ′-, and resonance frequency fR controlled through varying the number of coil turns, N. Based on an equivalent lumped parameter model, the special permeability spectrum shape and the dependence of permeability parameters on N are deduced for the metamaterial. The theoretical prediction is well consistent with the experimental results. [ABSTRACT FROM AUTHOR]
