  The theoretical study of laser-induced heating of a transport cargo
microcontainer constituting a hollow dielectric microcapsule with water filling
and a light absorbing polymer shell is presented. By means of FDTD and FEM
techniques, the numerical calculations of optical field spatial distribution
inside and near the microcapsules are carried out, and the temporal dynamics of
temperature profiles of core-shell microparticles of various morphological
types (spheres, ellipsoids, boxes, cubes, cylinders) and microcapsule clusters
in different configurations is addressed. The spatial configurations of light
absorption regions are shown to be substantially dependent on the morphology of
the microcapsules. For isolated microcapsules, the most efficient laser heating
is realized in capsules of cubic and cylindrical shapes. When the capsules are
aggregated into the densely packed cluster, the characteristic heating depth of
the whole assembly is higher for cylindrical microcapsules. In sparse
microassemblies the square-shaped capsules are preferable for increasing the
efficiency of laser heating.
