✦ Synopsis

Electromagnetic pulse propagation in an arbitrary disper-si¨e medium is in¨estigated. A quasimonochromatic pulse is assumed, and for this case, separate analytical in¨estigations for two cases of dispersion, called linear and quadratic dispersion, are carried out. Exact and con¨enient calculation formulas for en¨elopes of rectangular and ( ) trapezoidal triangular initial pulses in the case of linear dispersion are obtained. The same is obtained for a rectangular initial pulse in the case of quadratic dispersion. On the basis of this obser¨ation, the appropriate calculation formulas for an arbitrary initial pulse gi¨en by step-size amplitudes are created. The pulse distortion in the general case when it is impossible to separate linear and quadratic dispersion is in¨estigated. The obtained formulas are con¨enient for practical calculations.
