Alù Creates First 3D Invisibility Cloak
UT ECE professor Andrea Alù and colleagues at the UT Applied Research Labs have successfully created a cloaking device capable of hiding a 3D object in free space from microwaves. To create the device, the team used a plasmonic metamaterial shell to cover the object being cloaked. The cloak, based on a plasmonic metamaterial, can hide a cigar-sized cylinder from microwaves – it currently only operates for one microwave polarization.
