Abstract

The Lorentz–Mie theory is applicable to calculating scattering characteristics of spherical shaped particles. It is often applied to slightly non-spherical particles where its range of validity is uncertain. This paper defines the range of validity of the T-matrix technique of Barber and Hill as applied to homogeneous spherical and non-spherical particles. Scattering calculations are made for a set of non-absorbing homogeneous spherical particles with the origin of the particle offset over a certain range. The numerical results show that even for small offset value with the same input parameters, the phase function, extinction and scattering cross sections differ quite significantly compared to the generalized Lorentz–Mie technique known to give accurate scattering characteristics for spherical particle.
