Abstract:

Absorption power in a bounded internal part of a particle is described by semianalytical expressions obtained on the base of two different approaches (surface Poynting integral and volume integral) within the frameworks of Mie theory applied to a homogeneous sphere. This enables one to estimate heat release from “hot” points. The expressions are simplified with the allowance for contribution from only one resonant mode. The developed algorithms and programs are efficient from the computational viewpoint. Illustrative calculations are performed for water particles excited at laser wavelengths and for some model particles in the presence of morphological absorption resonance.
