Experimental demonstration of an efficient thermal concentrator. (a) Schematic of the fabricated concentrator by the combination of two SSTM units. (b) Experimental verification of concentrating property in uniform thermal field. (c) Calculated temperature distribution along x-axis. The inset shows the heat flux lines. (d) Experimental verification of concentrating property in the presence of a point heat-source, emitting cylindrical heat fronts.
