Propagation and reflection of plane elastic waves in the acousto-optic crystals tellurium dioxide and calomel as well as in the ferroelectric material barium titanate is examined in the paper. The reflection of the waves from a free and flat boundary separating the crystal and the vacuum is investigated in the (001) planes of TeO2, Hg2Cl2, and BaTiO3 in the case of glancing acoustic incidence o...

The aim of this paper is to develop a mathematical framework for acousto-electromagnetic tomography and to introduce an efficient reconstruction algorithm. In electromagnetic wave imaging, the resolution is limited by the Rayleigh criterion, that is, half the operating wavelength. By mechanically perturbing the medium, we show that it is possible to achieve a significant resolution enhancement....

For the study of parametric excitation, we have considered that the origin of Stimulated Brillouin Scattering (SBS) nonlinear interaction lies in the third-order optical susceptibility in a centrosymmetric, doped semiconductor which is subjected to transverse magnetic field. The third-order optical polarization in a SBS system arises due to nonlinear current density and acousto-optical strain o...

A recent theoretical paper [1] proposes a scheme for entanglement swapping utilizing acousto-optic modulators without requiring a Bell-state measurement. In this comment, we show that the proposal is flawed and no entanglement swapping can occur without measurement.
