✦ Synopsis

After a brief survey of Euclidean heat sources distribution behaviour in Euclidean spaces we will show how a distribution of fractal sources behaves in Euclidean spaces. The main applications deal with rough surfaces which can be mapped to fractal structures. In order to describe heat diffusion in heterogeneous media, the dimensionality of the diffusion process has to be introduced. We will illustrate this theroetical approach with experimental data obtained by using a short laser light pulse for heating and an infrared detection to monitor the surface temperature.
