Abstract: Generation processes of a photoacoustic response of a layered polyethylene/hydrogel structure by its irradiation with periodically modulated light have been experimentally studied. The heat sources are located in a gel near the interface with polyethylene. The response in the form of the pressure oscillations occurs as a result of the thermoelastic strain of the polyethylene layer by its thickness-nonuniform heating by a thermal wave. The obtained results can be useful for modification of the techniques based on the diffusion processes in gels.
Keywords: photoacoustic effect, temperature wave, “drum effect”, modulated light, agarose, gas-microphone method, thermoelastic deformation, diffusion, hydrogel.
