The idea was transformation optics , a scheme that tells scientists how to tailor the properties of a metamaterial to achieve an effect like cloaking .
这个想法是光学的转换,用一个设计来告诉科学家如何调整这种性能的材料来达到一种隐形的效果。
Instead use an email cloaking script whenever you need to show your email address .
而使用电子邮件时,你必须假借文字显示您电子邮件地址.
That same year , uc berkeley physicist xiang zhang and colleagues created the first cloaking device that worked in three dimensions .
Using nanofabrication techniques , the researchers etched tiny holes into the nitride to make a desired pattern , giving the waveguide the cloaking refractive index profile .
通过纳米制备技术研究者在氮化硅中刻蚀出许多空洞以构成所需图案,使得波导具有合适的隐形折射率。
Unlike existing optical cloaking devices , which are little more than toys , dr guenneau 's idea would have an immediate practical application : protecting heat-sensitive components in electronic devices .
