We theoretically find that a bi-layer structure composed of two kinds of dispersive metamaterials can possess an asymmetric reflection spectrum due to Fano-type interference between a discrete reflection resonance and a broadband strong reflection. The discrete reflection resonance appears at the frequency around which the dispersive permeability is near to zero at oblique incidence. Based on analytical and numerical analysis, the asymmetric factor in the Fano-type reflection is found to be linked with the angle of incidence.
