Evolution of the Precursor Fields,mations developed on Chap.6 for the saddle-point locations and the behavior of the complex phase function φ(ω,θ)at the saddle points are used and the advanced asymptotic techniques reviewed in Chap.5 are applied. Applications of the approximations from Chap.6 yields approximate expressions describin歌唱队 发表于 2025-3-24 07:15:16

The rigorous analysis of the dispersive pulse propagation phenomena is complicated by the simple fact that the dispersive and absoptive parts of the medium response are connected through the physical requirement of cas
