论超光速传播与信息速度

On Superluminal Propagation and Information Velocity

Akhila Raman

摘要:

本文探讨了最近的一些超光速传播的实验。众所周知,索末菲和布里渊分析了矩形正弦信号通过色散介质传播,并导出了描述前兆和主信号的表达式。本文利用泰勒级数展开法导出了这种色散介质的脉冲响应的精确表达式,并证明了对于小于真空渡越时间的时间$t$,对于任意因果输入信号,输出信号为零,并分析了超光速信息速度的含义。

英文摘要:

This paper examines some of the recent experiments on superluminal propagation. It is well known that Sommerfeld and Brillouin analyzed a rectangular sinusoidal signal propagating through a dispersive medium and derived expressions to describe the precursors and the main signal. In this paper, the impulse response of this dispersive medium is derived as exact expression using Taylor series expansion and output signal for any causal input signal is shown to be zero for time $t$ less than vaccum transit time and implications for superluminal information velocity is analyzed.
