Debye series of light scattering by a coated microbubble

Debye series for plane-wave scattering by a coated microbubble is derived. Being a rigorous solution of Maxwell equations, Debye series expands the Mie scattering coefficient into an infinity series, and clarifies the physical origin of scattering. The results for various p_max are computed and compared. The contributions of various scattering processes to far-field scattered intensity are isolated from total scattered intensity. The effect of coating including thickness and refractive index to far-field scattered intensity is discussed.
