High-order approximations to the Mie–series for electromagnetic scattering in three dimensions
Approximations to the Mie–series are fundamental in many applications. In particular, for validation of efficient electromagnetic scattering algorithms (to compute the radar cross section of three dimensional targets) or to understand the electromagnetic scattering by rain drops, it is important to evaluate the Mie–series with accuracy close to machine precision. In this paper, we propose a qua...
متن کاملTime-Dependent Lorentz-Mie-Debye Formulation for Electromagnetic Scattering from Dielectric Spheres
Canonical solutions to frequency domain Maxwell’s equations, in the spherical coordinate system, have found extensive use as is evident from citations in the scientific literature. What is conspicuous by its absence is lack of such expressions for transient Maxwell systems. The existence of such expressions or approximations, provide the means to glean interesting physics in a variety of applic...
متن کاملCoherence effects in Mie scattering.
The scattering of a partially coherent beam by a deterministic, spherical scatterer is studied. In particular, the Mie scattering by a Gaussian Schell-model beam is analyzed. Expressions are derived for (a) the extinguished power, (b) the radiant intensity of the scattered field, and (c) the encircled energy in the far field. It is found that the radiant intensity and the encircled energy in th...
متن کاملNew Improvements for Mie Scattering Calculations
New improvements to compute Mie scattering quantities are presented. They are based on a detailed analysis of the various sources of error in Mie computations and on mathematical justifications. The algorithm developed on these improvements proves to be reliable and efficient, without size (x = 2πR/λ) nor refractive index (m = mR − imI) limitations, and the user has a choice to fix in advance t...
متن کاملA Computer Modeling of Mie-Scattering by Spherical Droplets Within the Atmosphere
The Earth’s atmosphere is an environment replete with particles of differ-ent sizes with various refractive indices which affect the light radiation traveling through it. The Mie scattering theory is one of the well-known light scattering techniques ap-plicable to modeling of electromagnetic scattering from tiny atmospheric particles or aerosols floating in the air or within the clouds. In this...
