Absphere

Abshere by Kuan Fang Ren is based on the rigorous theory to calculate various physical quantities in the interaction of a light beam with a homogeneous spherical particle or with a concentric layered refractive index gradient. ABSphere allows to calculate: (1) scattering diagrams, (2) radiation pressure (force) and torque exerted by a beam of light on the particle, (3). internal and external electromagnetic fields, (4). extinction, scattering and absorption sections. The forms of the beam considered in ABSphere: (1) circular Gaussian beam. (2) elliptical Gaussian beam. (3) Dungnut beam of 4 different polarizations, (4). Bessel beam (5).
