Electromagnetic field calculations for a sphere illuminated by a higher-order Gaussian beam. II. Far-field scattering.
نویسنده
چکیده
A previously developed theoretical procedure for determination of electromagnetic fields associated with the interaction of a higher-order Gaussian beam with a homogeneous spherical particle is used to investigate the effects of incident beam type on far-field scattering. Far-field scattering patterns are calculated for (0,0), (0,1), and (1,1) mode Hermite-Gaussian beams and for the helix doughnut mode beam. The effects of incident beam type on the angular distribution of far-field scattering, for both on-sphere-center and off-sphere-center focusing, are examined.

Electromagnetic-field calculations for a sphere illuminated by a higher-order Gaussian beam. I. Internal and near-field effects.
A theoretical procedure has been developed for the determination of internal and external electromagnetic fields that result from the interaction of a higher-order Gaussian beam with a homogeneous sphere. Specific calculations are performed for (1, 0), (0, 1), and (1, 1) mode Hermite-Gaussian beams and for doughnut mode beams of four different polarizations (radial, angular, arced, and helix). ...
متن کاملSpeckle statistics of electromagnetic waves scattered from perfectly conducting random rough surfaces
By means of the extinction-theorem method, previously reported by J. M. Soto-Crespo and M. Nieto-Vesperinas [J. Opt. Soc. Am. A 6, 367 (1989)], the intensity statistics of the s-polarized electromagnetic field scattered from randomly rough, perfectly conducting, one-dimensional surfaces are studied in the case of surface transverse correlation lengths larger than the wavelength. In particular, ...
متن کاملWave-amplitude synthesis applied to Gaussian-beam scattering by an off-axis sphere.
Electromagnetic scattering of a Gaussian beam by an off-axis dielectric sphere is treated by the sum-of-waves formulation, which is inherent in Lorenz-Mie theory. Each "wave" is a spherical eigenvector, defined in the natural frame of the scatterer, and the coefficient of that wave is the "wave amplitude." Decomposition of the beam into homogeneous plane waves lays the ground for a synthesis of...
متن کاملElectromagnetic Scattering of a Field Known on a Curved Interface Using Conformal Gaussian Beams
Asymptotic techniques have been successfully applied to compute electromagnetic wave radiation in various high-frequency engineering domains. Recent approaches based on Gaussian beams for tracking fields may overcome some problems inherent to the ray methods such as caustics. The efficiency of these methods is based on the ability to expand surface fields into a superposition of Gaussian beams....
متن کاملCalculation of radiation force and torque exerted on a uniaxial anisotropic sphere by an incident Gaussian beam with arbitrary propagation and polarization directions
On the basis of spherical vector wave functions and coordinate rotation theory, the expansion of the fields of an incident Gaussian beam with arbitrary propagation and polarization directions in terms of spherical vector wave functions is investigated, and beam shape coefficients are derived. Using the results of electromagnetic scattering by a uniaxial anisotropic sphere, the analytical expres...
