A unique class of engineered light-manipulating materials, known as metamaterials or structured materials, makes use of patterns of strongly interacting wavelength or sub-wavelength-sized elements. Because of these intricate internal and surface structures, new properties have emerged, some exhibiting behavior that has resulted in rewriting long-understood “laws” for how light and other electromagnetic (EM) waves interact with materials. These materials have been opening up new options for controlling EM waves in many technological arenas, among them imaging, thermal control, and frequency conversion. Specific applications include night-vision, heat reflection and management in aircraft engines, and temperature regulation of electronics on satellites in the hot-and-cold extremes of space.

Hypersonic vehicles fly through the atmosphere at incredibly high speeds, creating intense friction with the surrounding air as they travel at Mach 5 or above – five times faster than sound travels. Developing structures that can withstand furnace-like temperatures at such high speeds is a technical challenge, especially for leading edges that bear the brunt of the heat.

The Defense Sciences Office is holding a Proposers Day meeting and webcast to provide information to potential proposers on the objectives of the new Materials Architectures and Characterization for Hypersonics (MACH) program. MACH seeks to develop new materials and designs for cooling the hot leading edges of hypersonic vehicles traveling more than five times the speed of sound.

Webcast
DARPA's Defense Sciences Office is sponsoring a Proposers Day webcast to provide information to potential proposers on the objectives of an anticipated Broad Agency Announcement (BAA) for the Nascent Light-Matter Interactions (NLM) program. The Proposers Day will be held via prerecorded webcast on November 28, 2017 from 1:00 PM to 2:00 PM. Advance registration is required for viewing the webcast.
The Materials Architectures and Characterization for Hypersonics (MACH) program aims to develop and demonstrate new materials architectures for sharp, shape-stable, cooled leading edges for hypersonic vehicles. The program will investigate innovative approaches that enable revolutionary advances in the materials, design and implementation of shape-stable, high heat flux capable leading edge systems.
