When most people think of invisibility cloaks, they think of something from Harry Potter, donning a fabric that makes you blend right into the background. that might help you sneak into the restricted section of your school library, but that won’t fool radars

A team of engineers at Iowa State University published a research paper detailing the use of flexible metamaterials — man-made materials that have properties **t found in nature — to cloak objects from microwave radar detection.

The team dubbed the radar-absorbing metamaterial "meta-skin," which consists of a matrix of liquid metal split-ring resonators embedded in layers of silicone rubber. The liquid metal alloy is a mix of gallium and indium called galinstan, which stays liquid at room temperature but is **t toxic like mercury. These split-ring resonators work by absorbing radar waves within specific frequency ranges. Read more...
