Asymmetrical E-shaped metamaterial is investigated in this paper. Numerical simulationsdisclose the two electromagnetic resonances and the superwide negative-refractive bandof this structure. The distributions of the induced current inthe E-shaped copper wires show that these two electromagnetic resonancesoriginate from the current flowing in the different C-shaped rings.The retrieved negative-refractive band is superwide, and the negative refractionwith high transmission occurs in the different bands. The metamaterialwith two or even more electromagnetic resonances offers an opportunityfor the realization of wide-band negative refraction.
