Optical beam diffraction tensor in birefringent crystals
Konstantin Yushkov, Natalya Naumenko
We demonstrate that anisotropy of Fresnel diffraction in a birefringent medium can be quantitatively characterized by a planar tensor. Eigenvectors of the tensor correspond to dire…

A Very-High-Velocity Acoustic Wave on a LiNbO/Sapphire Substrate for Use in Sub-6-GHz Devices
Natalya F. Naumenko
This letter presents a numerical investigation of acoustic modes propagating in an LiNbO/sapphire substrate under a periodic Al grating, demonstrating the occurrence of longitu…

Extreme acoustic anisotropy in crystals visualized by diffraction tensor
Natalya Naumenko, Konstantin Yushkov, Vladimir Molchanov
Acoustic wave propagation in single crystals, metamaterials and composite structures is a basic mechanism in acoustic, acousto-electronic and acousto-optic devices. Acoustic anisot…
