Researchers at GA Tech Research Institute (GTRI) are developing a novel heat-transfer material for powerful radar systems with a goal of removing heat up to 100 times more effectively than present materials. The novel material is a composite of diamond and copper that is trying to achieve thermal conductivity of up to 20,000 watts per meter K compared to 200-300 watts per meter K for copper. This would be achieved by using a materials systems approach that would also include liquid cooling. The project is funded by DARPA targeting high power T/R module packages.
