Abstract
We study extinction efficiency, absorption efficiency, and forward and backscatter efficiency for rotationally symmetric particles of the form r(θ) = ro[l +εTn(cos θ)]. Using the Extended Boundary Condition Method, as embodied in a computer code from Dr. Peter Barber, we have compared the various efficiencies, for T2- and T4-particles and 0 < ε ≤ 0.2, with the corresponding results for equal-volume and equal-projected-area spheres. A range of 0 to 10 in equivalent Mie size parameter x was considered, and results are given for nose-on incidence, for random orientation, and for random orientation plus a running mean over a size interval Δx = 1.
