## Abstract A wide‐band finite‐difference–time‐domain beam propagation method (FD TD‐BPM) based on Padé approximants is introduced to improve the bandwidth of the conventional TD‐BPM. Numerical dispersion relations for the TD‐BPM are derived to demonstrate the increase in bandwidth of the wide‐band

The ozone-decomposition flame has been studied by means of fourth-and second-order accurate schemes. The fourth-order methods include a method of lines, a time-linearization algorithm, and a rnajorant operatorsplitting technique. The second-order schemes include two time-linearization methods which
