Fig. 6: Scaling of location of caustics for power law correlation function.
From: Branched flows of flexural waves in non-uniform elastic plates
Finite element elastodynamic simulations confirm that using a power law correlation function of the form \(A(x,y)=(1+({x}^{2}+{y}^{2})/{L}_{{{{{{\rm{c}}}}}}}^{2})^{-2}\) instead of a Gaussian correlation to construct \(h(x,y)\) does not affect the predicted scaling of the location of the first caustic. Note that this a log-log plot. Markers indicate the mean. A 2-standard-deviation width centred at the mean is indicated by a vertical line.
