Popular Mechanics: How Metamaterials Could Lead to Invisible Tanks and Super-Stealthy Submarines
New construction materials made of composites could make military vehicles—and even soldiers—invisible to radar, sonar, and even the naked eye.
* Metamaterials are composite materials designed to manipulate light, radar, and sonar waves.
* Objects made of metamaterials could render themselves invisible to most types of sensors—including the human eye.
* Metamaterials are difficult to make and still a ways from mass production.
The development of new so-called metamaterials could lead to dramatic advances in military technology, particularly the ability to hide from sensors—even the human eye. Metamaterials, engineered composites designed to manipulate the electromagnetic spectrum, could lead to “invisible” tanks and armored vehicles, submarines undetectable by sonar, and weapons with improved seekers and guidance systems.
The big caveat though is that metamaterials are currently pretty difficult to manufacture and are still years away from full-scale production.
