Abstract A matrix formalism is introduced here for the analytical calculation of the thermo-elastic response of one-dimensional optically inhomogeneous layered structures exposed to the periodic laser heating. The multilayer structure consists of thermally and mechanically homogeneous solid layers which can be interleaved by liquid ot galore interlayers. The method enables the modelling of photoacoustic and photothermal measurements in a variety of engineering applications.

Altmetric calculates a score based on the online attention an article receives. Each coloured thread in the circle represents a different type of online attention. The number in the centre is the Altmetric score. Social media and mainstream news media are the main sources that calculate the score. Reference managers such as Mendeley are also tracked but do not contribute to the score. Older articles often score higher because they have had more time to get noticed. To account for this, Altmetric has included the context data for other articles of a similar age.
