On transverse radiation pressure cross-sections in the generalized Lorenz–Mie theory and their numerical relationship with the dipole theory of forces

Résumé

The Rayleigh limit of the generalized Lorenz–Mie theory (GLMT) and its relationship with the dipole theory of forces is investigated for transverse radiation pressure cross-sections and optical forces exerted over very small particles. If, at one hand, the GLMT provides interesting insights in terms of a multipole expansion and becomes restricted to contributions from (n=1)-partial waves, on the other hand the dipole theory incorporates the total electromagnetic fields and their interaction with an electric dipole. Simulations reveal an extreme accuracy between both approaches up to 3000 decimal places, thus reinforcing the conjecture that the Rayleigh limit of the GLMT might exactly identify with the traditional dipole theory of forces, although mathematically such identification remains to be uncovered.
