COMPUTATIONS OF SCATTERING MATRICES OF 4 TYPES OF NONSPHERICAL PARTICLES USING DIVERSE METHODS

The scattering matrix as a function of scattering angle has been compu ted for four different homogeneous particles: a prolate spheroid, an o blate spheroid, a finite cylinder and a bisphere with touching compone nts. The directions of the incident and scattered light beams, as well as the rotation axis of each particle, lie in the same plane. The par ticles considered have the same refractive index, volume and orientati on of the rotation axis with respect to the incident light. The comput ations were performed with the (superposition) T-matrix method, the se paration of variables method for spheroids and the discrete-dipole app roximation. The results are presented in the form of tables and graphs . Their usefulness as benchmark results and some other aspects are als o discussed. Copyright (C) 1996 Elsevier Science Ltd
