“…As in many other topics, CR has its analogous in sound waves by considering sonic crystals [34]. Most related works are purely theoretical [35][36][37][38][39][40] and only preliminary experiments have been reported [41][42][43]. However, all the phenomenology related to CR has been recovered for the acoustic case; namely the generation of conical structures when the incident bundle of waves propagate nearly parallel to the optic axis of the sonic crystal such that the state of polarization along the ring is linear, with the azimuth varying as e CR = (cos(φ/2), sin(φ/2)).…”

“…Rotation of the polarization in the plane D (e.g. in a circularly polarized wave) should create a precession of the energy flux P. This phenomenon called the internal conical refraction was theoretically predicted and experimentally discovered by De Klerk & Musgrave (1955). They found a circular cone of refraction along the 3-fold symmetry axis in the cubic crystal Ni.…”

“…We shall analyse in detail the mentioned above geometrical peculiarities and polarization singularities related to a pair of the so-called singular acoustic axes representing a new type of stable degeneracy and arising as a result of the considered split of a conical acoustic axis. On this basis we shall develop an extension of the classical theory of internal conical refraction (Barry & Musgrave, 1979;De Klerk & Musgrave, 1955;Fedorov, 1968;Khatkevich, 1962b;Musgrave, 1957) for an absorptive crystal. As will be shown, the damping provides very radical and non-trivial modifications of fundamental features of the phenomenon.…”
