title: TM-wave propagation controlled by split ring resonator array.
abstract: We propose a new approach to control the propagation of electromagnetic (EM) wave with certain polarization by a split ring resonator (SRR) array. Interactions between SRR and the EM wave in the array are analyzed and it is found that the H field is always perpendicular to the SRR plane around the magnetic resonance frequency. Based on this property, a semicircular waveguide is designed to realize a 180 degrees bending with high performance. The structure of this approach is simple and feasible, providing an alternative way to construct bending waveguide with low loss.
