It may sound like science fiction, but it’s not: UT researchers have successfully engineered a way to completely cloak an object, making it invisible.
Assistant professor Andrea Alù and his team in the Department of Electrical and Computer Engineering used a technique called plasmonic cloaking to make an 18-inch cylinder invisible on the microwave spectrum.
That means the cylinder was still perfectly visible to the human eye—but the hope is that someday the same technique can be applied in the real world.
This video, from the Texas Advanced Computing Center, explains the research in detail.
