In such a medium, the direction of the Poynting vector monochromatic plane wave is antiparallel to that of its phase velocity. Because of that, DNG displays some unusual electromagnetic properties such as backward-wave effect, negative refractive effect, perfect lens and a limit situation, zero index of refraction materials.

在這種材料中激情性欧美图片小说，單色均勻平面波的相速方向和坡印亭矢量方向是相反的免费。色婬，因此使雙負材料表現(xiàn)出一系列反常的電磁特性如：回波效應(yīng)、負折射效應(yīng)日韩精品毛色视频在线观看、完美透鏡效應(yīng)和一種極限情況即零折射率材料等美女操逼视频污网站。

The shift in the peak extinction wavelength and the change in the corresponding intensity of the LSPR band as a function of the refractive index of the solution are 71 nm/RIU and 0.21 a.u./RIU, respectively. The penetration depth of the electromagnetic field excited by LSPR upon the response of the sensing film is estimated to be about 16 nm.
