Scientists create ‘invisibility cloak’February 2nd, 2011 - 8:46 pm ICT by Aishwarya Bhatt
London, Feb 2 (THAINDIAN NEWS) British scientists have taken a huge step towards the age-long dream of invisibility.
The research by scientists from the University of Birmingham has a promising future because the crystal cloak that they have developed can actually make things like pins and paper clips ‘disappear’. The scientists explained that the trick behind the disappearance is split light.
The scientists with the help of researchers from Denmark placed two triangular calcites together. They then placed the resulting piece on a mirror. When light entered the calcite, it split into different polarizations on two rays with different speed.
The invisible effect is then created. The calcite however remains visible. The scientists believe that with this done, much bigger things could be hidden in the future.
The research was led by Dr. Shuang Zhang. He called the research a huge step towards making bigger things invisible in the future. He said that the finding was most interesting because it was the first time a natural object was being used to achieve invisibility.
The research and the progress made were published in the journal Nature Communications. It is published under the title, Microscopic Invisibility Cloak of Visible Light.
