摘要

本文用时域有限差分算法给出了波导中入射场的重建方法，研究了波导中脉冲传播的吸收边界条件。用本文的方法，只要测量出波导出口面上任一位置的场随时间的变化曲线，即可实现入射场的精确重建。

Abstract

In this paper

the reconstruction method of the incident field in a waveguide is presented by using of the finite-difference time-domain algorithm

and the absorbing boundary condition for pulse wave propagations in waveguides is studied. If the time-varying curve of the field at any position in the exiting plane of the waveguide is measured out

the accurate reconstruction of the incident field can be implemented by applying the method presented in this paper.
