A one-dimensional diatomic meta-chain with equal-size holes and different-length slits is designed. Broadband coherent magnetic plasmon waves (MPW) are formed in such a system, excited by both the electric resonance in the slits and the magnetic resonance in the holes in a wide range of incidence angles (0 1.IntroductionAlthough the invention of metamaterials has stimulated the interest of many researchers and has important applications in negative refraction [1][2][3][4][5][6], invisible cloaking [7][8][9], and many other transform optical designs, the basic design idea is very simple: composing effective media from many small structured elements and controlling their artificial electromagnetic (EM) properties. According to the effective media model, the coupling interactions between the elements in metamaterials are somewhat ignored; therefore, the effective properties of metamaterials can be viewed as the "averaged effect" of the resonance property of the individual elements. However, the coupling interaction between elements should always exist when they are arranged into metamaterials. Occasionally, especially when the elements are very close, this coupling effect is not negligible and will have a substantial effect on the properties of the metamaterials.

“…The propagation in linear arrays of SRRs in axial (i.e., wavevector is in the same direction of the magnetic dipole moment describing the SRR) or transverse (i.e., wavevector is in the transverse direction of the magnetic dipole moment describing the SRR) configuration has been studied experimentally in [2], and similar works (including theory) have been shown in [3][4][5]. The dispersion properties of a biperiodic linear array of SRRs (contiguous loops are loaded with different capacitances) have been shown experimentally in [6] to support MI waves in two distinct frequency bands. The same phenomenon has been studied thoroughly in linear arrays in [7] by having also a unit cell with two SRRs whose relative distance is smaller than the period.…”

Abstract-Magnetoinductive waves in arrays of split ring resonators (SRRs) have been previously investigated. Here we characterize modes with real and complex wavenumber in two dimensional periodic arrays of SRRs. Each SRR is modeled as a single magnetic dipole, and the retrieval of the complex modal wavenumbers is performed by computing the complex zeroes of the homogeneous scalar equation characterizing the field in the array. The required periodic Green's function is analytically continued into the complex wavenumber space by using the Ewald method. The proposed method allows for the description of each complex mode when varying frequency, complementing previous investigations. In particular, we analyze proper and improper, bound and leaky, magnetoinductive waves.

Magnetic metamaterials consist of small metallic resonators of the split ring type. Microscopic properties of these structures are governed by near field coupling between individual elements. This strongly anisotropic coupling leads to propagation of slow magnetoinductive waves with the wavelength much shorter than that of the electromagnetic radiation. This opens up novel possibilities of designing miniaturised subwavelength waveguide components and near‐field lenses in a wide range of frequencies, from radio frequencies, with a potential for medical applications in MRI, to the IR and visible range, aiming at fast signal processing. This paper provides an overview of contributions that led to the birth of the subject of magnetic metamaterials. The properties of slow waves on magnetic metamaterials including their dispersion characteristics, excitation and applications are discussed. The emphasis is laid on phenomena such as backward and forward slow waves, polaritonic hybridization of the interaction of a metamaterial with an incident electromagnetic wave yielding negative values of magnetic permeability, the possibility of positive and negative refraction of slow waves as well as mechanisms for near field subwavelength imaging.
