Photon polarisation in light-by-light scattering: finite size effects
We derive a simple expression for the photon helicity and polarisation-flip probabilities in arbitrary background fields, in the low energy regime. Taking the background to model a focused laser beam, we study the impact of pulse shape and collision geometry on the probabilities and on ellipticity signals of vacuum birefringence. We find that models which do not account for pulse duration can o...
متن کاملLight scattering by cubical particle in the WKB approximation
In this work, we determined the analytical expressions of the form factor of a cubical particle in the WKB approximation. We adapted some variables (size parameter, refractive index, the scattering angle) and found the form factor in the approximation of Rayleigh-Gans-Debye (RGD), Anomalous Diffraction (AD), and determined the efficiency factor of the extinction. Finally, to illustrate our form...
متن کاملLight propagation control by finite - size effects in photonic crystals
We exhibit the strong influence on light propagation of the finite size in photonic band-gap material. We show that light emission can be controlled by the symmetry group of the boundary of the finite device. These results lead simply to important practical applications. Photonic crystals are expected to permit the realization of devices for integrated optics or laser microcavities [1–5]. The t...
متن کاملBacteria Size Determination by Elastic Light Scattering
Light extinction and angular scattering measurements were performed on three species of bacteria with different sizes and shapes (Pseudomonas aeruginosa, Staphylococcus aureus, and Bacillus subtilis). The Gaussian Ray approximation of anomalous diffraction theory was used to determine the average bacteria size from transmission measurements. A rescaled spectra combining multiple angular data wa...
متن کاملScattering polarization due to light source anisotropy
Expressions are developed for the flux and polarization of radiation scattered by a spherically symmetric envelope for a central point stellar light source that radiates anisotropically. These are obtained in terms of the components of the spherical harmonics of the flux anisotropy from the source. Such anisotropy can arise from stellar spots, or from distortion of the star through rotation, pu...
