What is meant by efficiency?
25 Feb 2009
The efficiency (factors) scattering, and absorption are their corresponding, normalized cross sections, that is, the cross section divided by the cross-sectional area of the particle.
For instance, the extinction efficiency = (extinction cross section)/(cross-sectional area)
For further reference, please see “Absorption and Scattering of Light by Small Particles” by C.F. Borhen and D.R. Huffman, Wiley-VHC, 2004, pg. 71-72.
