Abstract
An enhancement technique of phase-shifting nonreciprocity in normally magnetized ferrite metamaterial lines is proposed by applying a slow wave structure based on spoof surface plasmon. The nonreciprocity is further enhanced by inserting an appropriate value of capacitance in the corrugated metallic strip. Metamaterial lines with high dispersive characteristics and large nonreciprocity were numerically designed and demonstrated in the experiment.
