The role of slit in stop band of periodical narrow slit metal tubes
二维开缝金属圆管带隙结构禁带特性中缝参数的研究

The band gap of two-dimensional metal tube structure with multi-width narrow slits is simulated and verified experimentally. The unique properties of the stop band exist in the band gap structure with combined parameters of slit tubes. It is found that the band gap of this structure is large and the starting frequency is low. In contrast to the band gap of the structure with narrow slits, the stop band of the combined structure of the parameters of the slits is continuous and large.
