中国和新加坡研究人员联手研制出新型隐身设备。
       A joint team of Chinese and Singa-porean researchers have developed an “invisibility cloak(隐形斗篷)”using devices made of glass.NowYou See Me, NowYou Don’t(九年级阅读) - 称子英语 - 孙广趁教育教学工作室
 
  Professor Chen Hongsheng of the Electromagnetics Academy(电磁学院)at Zhejiang University and a research team from Singapore’s Nanyang Technological University(南洋理工大学)successfully used a hexagonal(六角形的)device to make a goldfish invisi-ble and made a cat“disappear”using a polygonal(多边形的)device.
  The devices are created with thin panels of glass that make objects invis-ible by bending light around them.The technology is still rudimentary(基本的),most effective when the light comes froma single angle.The devices can also only make objects invisible in a narrow spectrum(频谱)of light,the professor said.
  The team has attempted to simplify the technology.They chose to use glass to make the devices because it is trans-parent,has a smooth surface,can be obtained easily and does not need to be processed with nanotechnology(纳米技术).Chen said the devices can be used in the field of security,entertainment and surveillance(监视),adding that the research team would continue to en-hance the devices’capacities for mak-ing objects invisible and reduce their weights.
  The team published their complete research in an online journal,Nature Communication,last month.
