我们证明了完整的隧道光通过大规模的μ-负介质，它具有负磁导率，但正介电常数，通过构建一个准一维结构的侧支。对于具有单个侧分支的结构，总是存在透射峰，该透射峰可以通过改变侧分支的参数而容易地调谐。对于具有周期性侧支阵列的结构，透射峰被放大到一个频带，该频带具有左手性，并且可以通过改变两个相邻侧支之间的距离和侧分支的长度来调谐。
We demonstrate complete tunneling of light through large- scale mu-negative media, which has negative permeability but positive permittivity, by constructing a quasi-one-dimensional structure with side branches. For the structure with a single side branch, there always exists a transmission peak which can be easily tuned by varying the parameters of the side branch. For the structure with periodic array of side branches, the transmission peak is enlarged to a band, which exhibits left-handedness, and can be tuned by changing the distance between two neighboring side branches and the length of the side branch.
