TY - JOUR TI - Analysis of photothermal response of thin solid films by analogy with passive linear electric networks AU - Galović Slobodanka P AU - Šoškić Zlatan N AU - Popović Marica N JN - Thermal Science PY - 2009 VL - 13 IS - 4 SP - 129 EP - 142 PT - Article AB - The paper presents conditions that should be met in order to make the photothermal induced temperature variations of a solid sample analogous to the voltage variations of the electric network with passive linear elements. Further analysis shows that such analogy enhances experimental determination of the thermal properties of thin solid layers by photothermal frequency method.
