摘要：

An experimental demonstration of mu negative of the Bragg gap in a one-dimensional composite right/left-banded transmission line (CRLH-TL) is presented. In this structure, a band gap which is independent of the scale length and is insensitive to disorder may be mu negative (NING) or epsilon negative, depending on the value of loading lumped-element components. Another band gap, which is induced by Bragg scattering, depends on the scale length and is sensitive to disorder of the structure of transmission line. As far as CRLH-TL is concerned, it is shown that the Bragg gap can be considered as a single negative gap, furthermore, it is always a MNG gap no matter what the gap between left-handed passband and right-handed passband is a mu-negative gap or an epsilon-negative gap.
