We analyze the influence of the generalizations of hyperbolic (Cattaneo) heat equations
(GCE) on temperature profile and photoacoustic signal for the two-layer samples. The GCE …

The paper presents a generalized model of the photothermal response of a polymer sample.
The model is based on a linear non-Fourier heat conduction equation that considers thermal …

The objective of this paper is to present methodology of the precise and reliable
determination of thermal diffusivity and linear coefficient of thermal expansion of the …

In modern high-speed semiconductor electronics, there is a high-rate heating of components
that is affected by very fast relaxation processes. The relaxation times of these processes …

In order to make the photothermal effect detectable from a sample with low optical
absorption, an optically opaque layer must be applied on its surface. A model of optically …

The model of a photoacoustic gas-microphone signal in the time domain recorded in a
transmission configuration using a minimum volume cell is derived. This model takes into …

In this paper, the possibility of determining the thermal, elastic and geometric characteristics
of a thin TiO2 film deposited on a silicon substrate, with a thickness of 30 μm, in the …

We analyze an extension of the dual-phase lag model of thermal diffusion theory to
accurately predict the contribution of thermoelastic bending (TE) to the Photoacoustic (PA) …

This paper describes the influence of thin transparent film on thermal and elastic
characteristics of the two-layer sample consisting of the silicon substrate and thin TiO2 film …

This paper analyzes the influence of the anomalous diffusive effects caused by micro-scale
heterogeneity and kinetic and inertial thermal relaxations on the optically induced …
