Abstract :
In this study, we demonstrate novel asymmetric metamolecule arrays with multiple sharp resonances. They reveal a new Fano-like mode due to the collective excitation of the metamolecules. Q-factors as high as 38 have been achieved. In the future, such resonances could be used in sensor and filter applications.
