The 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 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.
متن کاملConical diffraction complexified: dichroism and the transition to double refraction
With dichroism (anisotropic absorption), the dielectric tensor of a crystal becomes non-Hermitian, and each optic axis (diabolical point) splits into two singular axes (branch-point degeneracies). For a Gaussian beam incident on a dichroic crystal in a direction near the singular axes, the polarized light beyond the crystal is given by the same diffraction integrals as for a transparent crystal...
متن کاملWave-vector and polarization dependence of conical refraction.
We experimentally address the wave-vector and polarization dependence of the internal conical refraction phenomenon by demonstrating that an input light beam of elliptical transverse profile refracts into two beams after passing along one of the optic axes of a biaxial crystal, i.e. it exhibits double refraction instead of refracting conically. Such double refraction is investigated by the inde...
متن کاملConical refraction for new classes of biaxial metamaterials
The study of conical refraction for media other than biaxial non-magnetic crystals has never been considered in the literature – as far as the authors are aware. Hence, in this paper, we investigate how conical refraction can arise for broader classes of biaxial metamaterials using a new classification scheme previously developed by the authors. Namely, conical refraction is shown to occur for ...
