Abstract

We consider propagation and absorption of a narrow-band signal in a homogeneous dispersive medium. It is shown that all signals can be divided into two qualitatively different classes, namely, holonomic and piecewise-holonomic signals. When propagating in an absorbing medium, the holonomic signals are attenuated obeying an exponential law and, therefore, almost disappear at a sufficient long path lengths. The piecewise-holonomic signals are attenuated significantly slower (obeying a hyperbolic law) and, therefore, continue to exist even at substantially longer paths.

窄带信号在色散介质中的吸收

我们考虑窄带信号在均匀色散介质中的传播和吸收。结果表明，所有信号可以分为两类性质不同的信号，即完整信号和分段完整信号。当在吸收介质中传播时，完整信号按照指数定律衰减，因此，在足够长的路径长度下几乎消失。分段完整信号衰减明显较慢（遵循双曲定律），因此，即使在相当长的路径上也会继续存在。
