Abstract

Summary

In this paper we present efficient wave mode separation operators in anisotropic media. These operators are constructed by local rotation of wave vector to direction where qP-wave is polarized. The deviation angle between wave normal and qP-wave’s polarization direction is spatially estimated using poynting vector. The proposed operators provide comparable results with those generated by classical space domain convolution operators in anisotropic media. In the meantime, the added computational cost by applying new operators is small when compared to divergence and curl operators as used in isotropic case. Synthetic results validate the effectiveness of the present operators.
