Abstract
Spectral characteristics of metamaterials made of arrays of novel cylindrical resonators coupled with a substrate are simulated. It is shown that, apart from the usual modes, these resonators support additional modes due to a special shape of the resonators and to the presence of a dielectric substrate. In addition to the main resonance, the spectral characteristic has a resonance peak depending on the width of the transverse slit of the cylinder and the dielectric permittivity of the substrate. The dependences obtained in this work can be used to develop novel dynamically controlled metamaterials.
