We construct a flat-top filter by use of a tri-layer structure with AENG and AMNG metamaterials. Transfer-matrix method is used to calculate the transmittance of our tri-layer structure, and results show that two tunneling modes emerge at some frequencies and then will merge with each other, thus a flat-top filter is realized. We also show that metamaterial loss significantly reduces the transparent light, but does not change the transmittance distribution of light.
