摘要：

An exact asymptotic expression for thermal waves in an inhomogeneous semi-infinite condensed matter sample at high frequencies is derived. The theory also allows for a fast and accurate retrieval of subsurface thermal conductivity profiles from surface temperature values in response to incident modulated radiation.
