Abstract :
The magnetic resonance related effects on energy band diagrams of 3D metamaterials composed of cylindrical dielectric resonators are investigated for a wide range of dielectric permittivity of the resonator material. It is shown that at permittivity values exceeding some threshold, the effective negative permeability of the medium provided by magnetic resonances in DR arrays defines the 1st band-gap formation. Below threshold, in contrast, the resonance phenomena are responsible for the formation of the second transmission band providing for the negative refractive index of the medium.
