Abstract:This paper presents a new approach to the thermal characterization of
aluminum, based on the electro-acoustic analogy between the thermoelastic
component of the photoacoustic signal and the passive RC low-pass filter.
The analogies were used to calculate the characteristic thermoelastic
cut-off frequencies of the photoacoustic component and obtain their
relationship with the thickness of the aluminum samples. Detailed numerical
analysis showed that the required relationship is linear in the l… Show more
