从理论上研究了含有无限异向介质的一维光子带隙结构中的非线性传输特性。研究发现，当无限元材料为截止、抗截止和永不截止介质时，该复合结构在很低的归一化输入光强阈值下即可实现光学双稳.研究还发现，存在着与不确定超材料参数密切相关的横向位移。
Nonlinear propagation characteristics are investigated theoretically in a one-dimensional photonic band-gap structure containing indefinite metamaterials. It is found that optical bistability can be achieved at very low threshold values of normalized input intensity in this composite structure when the indefinite metamaterial is a cut-off, anticut-off, and never cut-off medium. It is also found that there exists corresponding bistable lateral shift which is strongly dependent on the parameters of indefinite metamaterials.
