A Basic Demonstration Of Optical Cloaking [Science]
posted February 11 2014 4:33.05 by spic0m




John Howell, a Professor of Physics at the University of Rochester, decided to tackle an unusual DIY project. With the help of his 14 year-old son, Benjamin, he built three simple, but surprisingly effective optical cloaking devices with inexpensive, off-the-shelf materials.

Cloaking is a common topic both in popular culture and in the scientific community. Cloaking means hiding an object from view at specific frequencies, and different types of cloaking have been recently demonstrated in labs around the world. Howell and his son built three different devices to show that it is possible to do optical, unidirectional cloaking cheaply, and for large objects.
