Scientists invent invisibility cloak 科學家發明隱形披風

It sounds like a far-fetched invention from science-fiction or fairytales.
But US scientists have developed a working invisibility cloak made from small particles of glass.
When light hits an object, it bounces off the surface and into the naked eye, making it visible. But researchers at Michigan Tech University have found a way of capturing infrared light and bending it around an object, making it invisible.
At the moment the science is still based in the lab. But if the same results could be achieved with visible light, the shrouded object would disappear from sight.
Professor Elena Semouchkina has developed a nonmetallic cloak that uses identical glass resonators made of chalcogenide glass, a type of material that does not conduct electricity.
In computer simulations, the cloak made objects hit by infrared waves—approximately one micron or one-millionth of a metre long—disappear from view.
It is the first time scientists have tried using glass to bend light in this way.

far-fetched:形容詞,牽強附會的。例句:I’m not conviced by your far-fetched excuse.(我不會被你牽強的理由說服。)
(be)made from:片語,(產生本質變化的)由……製成。例句:The paper is made from wood.(紙是木材做的。)「be made of」則表示由成品可看出原料,例句:The table is made of wood. (這張桌子是木頭製造的。)
chalcogenide glasses:科學名詞,硫系玻璃。是指以硫系元素硫(S)、硒(Se)與碲(Te)為主體的玻璃。
