dispersive medium

基本解釋

Then the possibility of larger phase velocity and group velocity than light speed in dispersive medium is discussed.
然后從色散介質(zhì)中相速度與群速度的關(guān)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.
這種復(fù)雜性使放置于遠(yuǎn)場(chǎng)的薄色散介質(zhì)對(duì)光脈沖同時(shí)產(chǎn)生時(shí)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(zhì)，在處理色散介質(zhì)中電磁波的散射和傳播問(wèn)題時(shí)，用移位算子處理有理分式法獲得FDTD計(jì)算中電位移矢量D和電場(chǎng)強(qiáng)度E的時(shí)域遞推關(guān)系。

色散媒質(zhì)
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.
最后本文首次給出的Extended_(FD)~2TD方法將集中參數(shù)包含到與頻率相關(guān)的介電常數(shù)中，可分析色散媒質(zhì)中含有集中元件的混合電路，進(jìn)一步擴(kuò)大了時(shí)域有限差分方法的應(yīng)用范圍。
