Popis: Combining traveling-wave ring resonators and microstrip inductors in a planar microstrip line circuit, negative values of electric permittivity and magnetic permeability can be obtained. This phenomenon arises from negative permeability of the traveling-wave ring resonators and negative permittivity due to the behavior of shorted stubs within the rejected frequency band. Thanks to the nonreciprocal behavior of the traveling-wave ring resonators we can achieve 16 dB isolation between s21 and s12 in the left-handed region. Therefore, a novel approach is presented here to synthesize a nonreciprocal magnetless left-handed media in microstrip technology. Full wave simulation results confirm the left-handed behavior of the interaction. The concept can be extended to active nonreciprocal network.
