Fifth-Order Corrected Electromagnetic Field Components for a Fundamental Gaussian Beam.

摘要

In two recent papers, 1,2 theoretical calculations have been presented investigating the electromagnetic interaction of a monochromatic fundamental Gaussian beam (i.e., a TEM00 mode focused laser beam) with a homogeneous spherical particle. A mathematical description of the electromagnetic field components of the incident Gaussian beam which accurately satisfies Maxwell's equations is required for these calculations. In Refs. 1 and 2, first-order corrected expressions developed by Davis3 were used for the incident Gaussian beam description. The first-order corrected Gaussian beam description, which is consistent with the first-order corrected expressions of Lax, Louisell, and McKnight4 and the development of Simon, Sudarshan, and Muhunda,5 has been found to give good results when the beam waist radius (Wo) is much greater than the wavelength lambda.
