From: Optimization-based design of heat flux manipulation devices with emphasis on fabricability

Heat flux concentration and cloaking example: (a) DMO-designed device, (b) temperature (colormap with isolines every 4 °C) and heat flux (arrows) in the whole plate, (c) temperature along y = 0 for the current DMO-designed device and the optimization-designed one with continuous metamaterial distribution9.
