Title: This funnel-shaped metamaterial, which we refer to as a heat spreader, acts as a point-to-plane heat source converter. We see that, in contrast to the nonuniform distribution of heat observed throughout the natural material, our design guides the flow of heat in a uniform manner - leading to a controlled, uniform temperature across the top surface. This is particularly useful in heat sink and heat plate applications where we wish to either maximise the rate at which heat is dissipated from the top surface or make sure that something is heated evenly. The realisation of metamaterials often presents a significant challenge - especially when the ideal properties exhibit both spatial and directional dependence. However, by carefully choosing our transformation we can accurately approximate our metamaterial regions with simple, rotated laminates. Therefore, a huge advantage of our metamaterial design is its simplicity. For more information on this topic check out our recent paper on heat spreaders: https://doi.org/10.1016/j.apm.2022.01.026
