While the Harry Potter series might have made the invisibility cloak famous, two researchers have discovered a way to make that fiction a reality. The Edward S. Rogers Sr. Department of Electrical & Computer Engineering have invented an authentic invisibility cloak that has the ability to adapt and change with different types and sizes.
PHD student Michael Selvanayagam and Professor George Eleftheriades are behind the innovative invention. By surrounding an object with small antennas that are able to radiate an electromagnetic field, the field cancels out waves that stem from the cloak thus making it appear invisible. Eleftheriades told reporters,”We’ve taken an electrical engineering approach, but that’s what we are excited about. It’s very practical…We’ve demonstrated a different way of doing it. It’s very simple: instead of surrounding what you’re trying to cloak with a think metamaterial shell, we surround it with one layer of tiny antennas, and this layer radiates back a field that cancels the reflections from the object.”
Demonstrating their new found approach to cloaking, the duo showed how the process works by cloaking a metal cylinder from radio waves. While still in the beginning stages, Eleftheriades says that the project can be scaled up to cover a larger surface area.
Hopes are high for this project as it develops. The invisibility cloak’s uses are endless as it can be used militarily as well as well as for everyday purposes.
