Conical 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 ...
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 کاملConical refraction as a tool for polarization metrology.
A method for polarization metrology based on the conical refraction (CR) phenomenon, occurring in biaxial crystals, is reported. CR transforms an input Gaussian beam into a light ring whose intensity distribution is linked to the incoming polarization. We present the design of a division-of-amplitude complete polarimeter composed of two biaxial crystals, whose measurement principle is based on ...
متن کاملConical diffraction: observations and theory
Conical refraction was produced by a transparent biaxial crystal of KGd(WO4)2 illuminated by a laser beam. The ring patterns at different distances from the crystal were magnified and projected onto a screen, giving rings whose diameter was 265 mm. Comparison with theory revealed all predicted geometrical and diffraction features: close to the crystal, there are two bright rings of internal con...
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.
