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 increased density of components in today’s electronics has pushed heat generation and power dissipation to unprecedented levels. Current thermal management solutions, usually involving remote cooling, where heat must be conducted away from components before rejection to the air, are unable to limit the temperature rise of today’s complex electronic components without adding considerable weight and volume to electronic systems. The result is complex military systems that continue to grow in size and weight due to the inefficiencies of existing thermal management hardware.
Unlike photonic sensors that exploit the photoelectric effect to enable infrared imaging at cryogenic temperatures, uncooled thermal sensors work by allowing an infrared absorbing material to be heated by incident electromagnetic radiation to produce an image. Such thermal sensing devices, also known as bolometers, have traditionally been less sensitive and slower than their cooled photonic analogs.
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.
Recent advances in our understanding of light-matter interactions, often with patterned and resonant structures, reveal nascent concepts for new interactions that may impact many applications. Examples of these novel phenomena include interactions involving active media, symmetry, non-reciprocity, and linear/nonlinear resonant coupling effects.
