N2 - In this work the thermal waves in a bounded solid are investigated taking into account the surface thermal conductivity, surface heat capacity and surface heat impedance. The last two concepts are delined by means of the heat diffusion equation to study the heat transport through the surface. The general boundary conditions to the thermal diffusion equation are obtained, and the temperature distribution is analyzed. Some special cases, depending on the correlation between the characteristic lengths involved in the heat diffusion and the light absorption are represented. It is shown that the modulation and non-modulation irradiation is absorbed on the surface or in the bulk in the different ways.
