Abstract:The angular spectrum of the Davis fifth-order linearly polarized, dual, and symmetrized fields of a focused Gaussian laser beam is obtained. Since the original Davis fields are not an exact solution of the vector wave equation and Maxwell's equations, a beam remodeling procedure within the angular spectrum is described that produces an exact solution. The spherical multipole beam shape coefficients of the remodeled beam are then obtained, and it is shown that in the weak focusing limit they simplify to the loc… Show more

“…A procedure was described that minimizes the standing wave contribution. In [37] an angular spectrum of plane waves was obtained for the Davis fifth-order focused Gaussian beam and a zero-order electromagnetic Bessel beam. The angular spectrum of the Davis beam was remodeled so that it now satisfies Maxwell's equations and the vector wave equation, whereas the original Davis approximation did not.…”

“…An attractive feature of this beam (this class) is the description of strongly focused (or strongly divergent) EM‐optical wave fields for , where k is the wave number. Lock discussed the angular spectrum of plane waves for the Davis fifth‐order focused Gaussian beam , and for a zero‐order electromagnetic Bessel beam. The angular spectrum of the Davis beam was remodeled so that it now satisfied Maxwell's equations and the vector wave equation, whereas the original Davis approximation did not.…”
Section: More Generalized Lorenz‐mie Theories For Various Beam Shapesmentioning
Generalized Lorenz-Mie theories form a set of analytical approaches dealing with the interaction between electromagnetic arbitrary shaped beams and a class of particles possessing enough symmetries to allow one to use the method of separation of variables. This paper provides a commented reference database concerning generalized Lorenz-Mie theories for the period 2009-2013.
