Research output: Contribution to conferencePaperResearchpeer-review


The absorption efficiency of a homogenous sphere illuminated by a plane electromagnetic wave can be found exactly using Lorenz-Mie theory and the Optical Theorem. The solution is expressed in terms of an infinite sum of spherical modes (see e.g. C. F. Bohren and D. Huffman, Absorption and scattering of light by small particles, Wiley, 1983, Chap. 4).
