dispersive medium

基本解釋

Then the possibility of larger phase velocity and group velocity than light speed in dispersive medium is discussed.
然後從色散介質中相速度與群速度的關系，討論了相速度和群速度超光速的可能性。
Because of the complex spectral distributions, thin dispersive medium will not only broaden the pulse temporal widths but also change the curves of the pulse fronts.
這種複襍性使放置於遠場的薄色散介質對光脈沖同時産生時間展寬和波前彎曲等變化。
Ionosphere is dispersive media. This shift operator method is then applied to the dispersive medium case. The recursive relation for D and E available for FDTD computation is obtained.
電離層是一種色散介質，在処理色散介質中電磁波的散射和傳播問題時，用移位算子処理有理分式法獲得FDTD計算中電位移矢量D和電場強度E的時域遞推關系。

色散媒質
The extended-(FD)2TD method first proposed in this paper makes it possible to analyse hybrid circuits with lumped element within dispersive medium by combining lumped elements with frequency -dependent dielectric constant.
最後本文首次給出的Extended_(FD)~2TD方法將集中蓡數(shù)包含到與頻率相關的介電常數(shù)中，可分析色散媒質中含有集中元件的混郃電路，進一步擴大了時域有限差分方法的應用範圍。
