Abstract:

Particular properties of formation of the optical field in the composite spherical microcapsules of different size consisting of a polymer absorbing shell and a non-absorbing liquid core are presented. The numerical simulation shows that changes in the thickness of the shell, grown on the core fixed radius, and the coefficient of its own radiation absorption determine the nature of spatial distribution and amplitude characteristics of the absorbed power. Variations in these parameters allow changing position and peak values of the areas of the effective absorption volume of the particle and, consequently, create conditions favourable for opening the shells in the appropriate spatial areas. This is important for the solution of practical tasks associated with the problem of release of the contents of the microcapsules.

Keywords:
