Abstract
Summary
In this paper we present two improved wave mode separation methods in anisotropic media. The proposed methods aim to efficiently implement wave mode separation while preserving properties of decomposed physical quantities from original elastic wavefields. The first approach is using vector decomposition which output decomposed wave modes with same amplitude, phase as the input wavfields. The second method is introducing amplitude and phase corrections to divergence-like and curl-like operators, then wavefields energy can be conserved in wave mode separation. Synthetic results verify the effectiveness of the proposed methods.
