| Abstract: | The scattering and absorption characteristics of the electromagnetic wave by a hollow or solid core-shell spherical particle are analyzed in this paper, based on the electromagnetic wave theory. The influence of geometrical and material parameters on the scattering and absorption of electromagnetic wave is discussed numerically and he analysis for the different ratios of incident wavelengths to particle sizes are carried out in detail. |

| Keywords: | core-shell particle scattering and absorption particle size back scattering attenuation coefficient |
