Polarization fingerprints in the clear blue skyPolarization fingerprints in the clear blue sky
<p>Daylight is polarized, the strength being greatest at points in the sky at right angles to the sun, and zero at four points: above and below the sun and anti-sun. The zero-polarization points are ‘fingerprint’ singularities, ...
Particle Acceleration by Radially-Polarized Laser BeamsParticle Acceleration by Radially-Polarized Laser Beams
<p>My recent work on direct acceleration in vacuum of particles (electrons, protons, ions and bare nuclei) using radially-polarized laser beams, will be presented. After a brief discussion of radially-polarized light, the ...
