Bessel Beams
Kirk T. McDonald
Scalar Bessel beams are derived both via the wave equation and via diffraction theory. While such beams have a group velocity that exceeds the speed of light, this is a manifestati…
Polarization Dependence of Emissivity
David J, Strozzi, Kirk T. McDonald
We deduce the emissivity of radiation from a metallic surface as a function of angle and polarization. This effect has found application in the calibration of detectors for cosmic…
Axicon Gaussian Laser Beams
Kirk T. McDonald
We deduce the simplest form for an axicon Gaussian laser beam, i.e., one with radial polarization of the electric field.
Time-Reversed Diffraction
Max S. Zolotorev, Kirk T. McDonald
We show that a time-reversed formulation of Huygens-Kirchhoff diffraction can be used to deduce the transverse and longitudinal fields of a Gaussian laser beam, starting from a sim…
