摘要：

An effective particle picture developed earlier for gap soliton propagation in piecewise uniform gratings is extended to treat gratings that vary gradually. In particular, we consider gratings in which the strength or the Bragg frequency varies linearly with position. We use this to analyze propagation in more complicated structures corresponding to localized grating defects, and gradual interfaces between two different gratings. [S1063-651X(98)07312-7].
