In cda: Coupled-Dipole Approximation for Electromagnetic Scattering by Three-Dimensional Clusters of Sub-Wavelength Particles

Description

Particles arranged along a helix

Usage

cluster_helix(N = 5, a = 10, b = 10, c = 20, R0 = 100, pitch = 200,
  delta = pi/5, delta0 = 0, right = TRUE, angles = c("helix", "random",
  "fixed"), seed = 123, ...)
