弱吸收介质平板对超光速脉冲的反射
Superluminal pulse reflection from a weakly absorbing dielectric slab
摘要：
从理论上研究了弱吸收介质平板反射光脉冲的群延迟，发现在平板共振（$Re(kd)=mπ$）附近，弱吸收介质平板反射光脉冲具有较大的负群延迟。反射和透射脉冲的群延迟将随着吸收的增加而饱和。
英文摘要：
Group delay for a reflected light pulse from a weakly absorbing dielectric slab is theoretically investigated, and large negative group delay is found for weak absorption near a resonance of the slab ($Re(kd)=mπ$). The group delays for both the reflected and transmitted pulses will be saturated with the increase of the absorption.
