Abstract :
We demonstrate the Fano resonance in reduced symmetry metamaterials with both inversion symmetry being broken, and show that two bright modes of perpendicular polarizations can be hybridized by this Fano resonance. Experimental results are shown and demonstrate the onset of Fano resonances as the coupling between the bright modes and the dark mode overcome resistive losses in the metal.
