Dependence of the Brillouin precursor form on the initial signal rise-time

Ciarkowski A.

Journal of Technical Physics

2003

Vol. 44, no 2

181-192

Propagation of a Brillouin precursor in a Lorentz dispersive medium is considered. The precursor is excited by a sine-modulated initial signal, with its envelope described by a hyperbolic tangent function. The purpose of the paper is to show how the rate of growth of the signal affects the form of the Brillouin precursor. Uniform asymptotic approach, pertinent to coalescing saddle points, is applied in the analysis. The results are illustrated with numerical examples.
