Abstract
A photoacoustic model of slightly inhomogeneous solids, which provides formulae for the surface temperature, surface displacement and the thermally induced Rayleigh wave, is reported. An example is given to demonstrate the potential of defining the thermal conductivity profile from the frequency dependence of the surface temperature.Keywords
