Fig. 2: Thermal characterisation of a hierarchical two-component bar with a heat bath at either end.
From: Thermal metamaterials for enhanced non-Fourier heat transport
The light (dark) green component has κ = 400 (40) W/m/K, and the bar has length L = 1 μm, with unit spacing U = 0.01 L. The left (right) heat bath is fixed to 400 (300) K. The bar is set to 300 K at t = 0 s. The temperature evolution at three points along the bar for a the Cattaneo model (solid), Fourier model (dashed) and b the difference between the Fourier and Cattaneo models.
