主信号在色散洛仑兹介质中的传播

Propagation of the main signal in a dispersive Lorentz medium

A. Ciarkowski

摘要:

本文研究了洛仑兹色散介质中主信号的演化。在介质中传播的信号由正弦调制脉冲信号激励,其包络由双曲正切函数描述。给出了信号的一致渐近表示和非一致渐近表示,并证明了一致渐近表示何时可化为非一致渐近表示。最后给出了数值算例。

英文摘要:

Evolution of the main signal in a Lorentz dispersive medium is considered. The signal propagating in the medium is excited by a sine-modulated pulse signal, with its envelope described by a hyperbolic tangent function. Both uniform and non-uniform asymptotic representations for the signal are found. It is shown when the uniform representation can be reduced to the non-uniform one. The results obtained are illustrated with a numerical example.
