The book consists of 3 chapters with 12 contributions written by world-leading experts in correspondent areas. The first chapter is devoted to the study of light scattering by a single particle and also by the ensembles of particles in the single scattering approximation valid for low concentration of scatteres. In particular, ligth scattering by ice crystals (1.1), soil particles (1.2) and biological particles (1.3) is considered. The authors pay attention to both theoretical and experimental results in the area.§In short, this volume gives a valuable picture of recent developments in the area. So the book has capabilities to further facilitate studies in teh area of light scattering media optics and be of importance for reasearchers across various scientific fields including astronomy, biophysics, combustion, meteorology, optics, remote sensing and geophysics.
