Convergence of Gaussian - Beam Modes in Corrugated Conical Horns
Gaussian beam-mode expansion with only the fundamental mode does not work properly when the angular region of interest is wide. It is necessary to use higher-order mode for the expansion. A study of the convergence of these higher order modes is presented for the case of a corrugated conical horn. Conclusions about the number of modes necessary for good accuracy are given. © 2005 Wiley Periodic...
متن کاملThe ins and outs of conical refraction
patriotic pride, who called conical refraction “the radiant stranger” in a florid passage in his memoirs. The two physicists responsible for the theoretical prediction and experimental confirmation of conical refraction were William Rowan Hamilton (1805-1865) and Humphrey Lloyd (1800-1881), both professors of Trinity College Dublin (fig. 1). Ireland’s recent Year of Hamilton (2005) provided an ...
متن کاملInterferometric characterization of the structured polarized light beam produced by the conical refraction phenomenon.
The interest on the conical refraction (CR) phenomenon in biaxial crystals has revived in the last years due to its prospective for generating structured polarized light beams, i.e. vector beams. While the intensity and the polarization structure of the CR beams are well known, an accurate experimental study of their phase structure has not been yet carried out. We investigate the phase structu...
متن کاملDiffraction of the Gaussian Beam on Layered Lens and Similar a Conical and Diffraction Axicons
In this paper we consider the possibility of replacing the diffraction axicon and the conical axicon on the gradient lens with a linear variation of the refractive index. Analytically and numerically using the finite-difference timedomain method we performed a comparative study of the Gaussian beam diffraction on diffraction mikro-axicon, conical axicon and gradient microlens consisting of subw...
متن کاملOn Conical Refraction in Hexagonal and Cubic Media
The occurrence of conical refraction in hexagonal and in cubic elastic media is investigated by the method of localizations. This is accomplished by generalizing the Atiyah–Bott– G̊arding theory from the scalar case to hyperbolic square systems of linear partial differential systems with constant coefficients.
