In this paper, a multi-layered metallic structure is proposed, which consists of split-ring resonators on both sides of two dielectric substrates. Numerical results reveal that the structure realizes a high magnitude of 0.94, three bands and broadband (more than 8 GHz) asymmetric transmission for linearly polarized wave. These properties are not observed in previous works. In order to better know these transmission properties, the Fabry-Perot like resonance model has been introduced to analyze the enhancement mechanism of asymmetric transmission in the multi-layered structure. The physical mechanism of linearly polarized wave conversion and asymmetric transmission based on electric fields and currents distribution is also analyzed in detail, respectively.
