Abstract ：We demonstrate experimentally a intriguing Fano-resonance in a perforated planar metamaterial with hole and slit pairs. The transmission strength of the Fano-resonance is modulated by interference between the composite diffracted evanescent wave and the direct transmission field instead of by the coupling between two plasmonic modes. Our metamaterials might have potential applications in future designs of plasmonic devices.
