ABSTRACT
Metamaterials are artificial engineered materials that can provide unusual electromagnetic properties. One of their most important properties is the feasibility of left-handed materials (LHM) from the combination of electric conductors. This chapter presents the design and measurement of Raman scattering (SR) with a mu-negative (MNG) response as well as their potential application as artificial magnetic reflectors (AMR). One potential application of the MNG magnetic resonators is to produce AMRs. The chapter discusses the potentials and limitations of fractal designs as MNG resonators. It aims to study different strategies to produce bi-frequency MNG responses using SRs. One fundamental property of the SRs is their smaller electrical size with respect to the SRRs, yielding to a higher degree of material homogenization, at the expense of a smaller fractional bandwidth. Artificial magnetic conductors are large screens composed of a periodic arrangement of magnetic resonators.
