G. Gouesbet et G. Grehan, INTERACTION BETWEEN A GAUSSIAN-BEAM AND AN INFINITE CYLINDER WITH THEUSE OF NON-SIGMA-SEPARABLE POTENTIALS, Journal of the Optical Society of America. A, Optics, image science,and vision., 11(12), 1994, pp. 3261-3273
A theory of interaction between a Gaussian beam described by a first-o
rder Davis approximation and an infinite cylinder, introducing scalar
potentials that are not linear combinations of separable potentials, i
s discussed. The theory exhibits unexpected difficulties, forming a ch
allenge that should attract the attention of other researchers.
