Mishchenko, M.I., 1990: Extinction of light by randomly-oriented non-spherical grains. Astrophys. Space Sci., 164, 1-13, doi:10.1007/BF00653546.

Waterman's T-matrix approach is used to derive a simple analytical expression for the extinction cross-section for randomly-oriented non-spherical grains. Numerical results are presented for randomly-oriented oblate and problate spheroids and Chebyshev particles composed of 'astronomical silicate'. These results are compared with those for spherical grains, and possible influence of the shape of dust grains on the value of interstellar extinction is considered. The range of validity of the Rayleigh approximation for computing extinction efficiency factors for randomly-oriented non-spherical grains is discussed.
