Voices From Darpa

We usually think of materials based on our experience in the natural world. For example, something that’s light is usually fragile (like a feather) or something heavy is usually strong (like a brick). But what if we could engineer a material that had completely new characteristics that defied properties found in nature? Engineered materials, also known as metamaterials, allow us to do just that. DARPA Program Manager Dr. Rohith Chandrasekar in DARPA’s Defense Sciences Office has led programs designing metamaterials that revolutionize how light interacts with matter. His programs are enabling new concepts for improving Warfighter effectiveness and health on the battlefield with new optics and materials. In this episode, Dr. Chandrasekar discusses several of these programs including Enhanced Night Vision in Eyeglass Form (ENVision), which has developed metamaterials to replace heavy and bulky binocular-like night-vision goggles lenses with lightweight lenses providing more infrared information and near eyesight
