A theoretical basis of calculations of interaction of electromagnetic waves with single particles and dispersed materials as applied to various problems of engineering is considered. Some recommendations based on simple physical models are given.

Spectral properties of single particles are considered including distribution of absorbed radiation power in the particles. A differential model for radiative transfer in large semi-transparent particles is presented. Some examples of practical application of this approach are discussed.

Transport approximation and simple differential models for radiative transfer in particle clouds and dispersed materials are presented. It is illustrated that these methods are sufficiently accurate in solving many important problems. Some examples are considered to demonstrate a wide use of the developed approximate approach in engineering calculations.
