The influence of spherical microcapsules on the spatial distribution of absorbed laser radiation power

Particular properties of formation of optical fields in composite spherical microcapsules of different size consisting of a polymer absorbing shell and a nonabsorbing liquid core are considered. The numerical simulation shows that changes in the thickness of the shell grown on the fixed-radius core and in the coefficient of proper radiation of the shell determine the nature of spatial distribution and amplitude characteristics of the absorbed power. Variations in these parameters allow changing the position and peak values of the regions of the effective spatial absorption of the particles and, consequently, create conditions favorable for opening the shells in the appropriate spatial zones. This is important for the solution of practical tasks associated with the problem of release of the encapsulated material. © 2016, Pleiades Publishing, Ltd.
