Abstract

Uniform asymptotic technique, developed by Bleistein and Handelsman, is applied to find asymptotic representation for the evolution of harmonic, amplitude modulated signal in a dispersive Lorentz medium. The results obtained are uniform in space and time and under mature space/time conditions recover Sommerfeld and Brillouin precursors followed by the main signal. In a special case Sommerfeld and here obtained results are in full agreement.
