Abstract

In the ac calorimetric thermal diffusivity measurement of a thin film with high thermal diffusivity, the reflection of ac temperature waves at the edge of the film is no longer disregarded. From a theoretical consideration, the condition required for the measurement on such a sample is proposed.
